Given that other instances of "{...}" in the revision documentation
represent literal characters of revision specifications, describing
the rev^-n shorthand as "<rev>^-{<n>}" incorrectly suggests that
something like "master^-{1}" is an acceptable form.

40069d6e3a submodule.c: correctly handle nested submodules in is_submodule_modified
Suppose I have a superproject 'super', with two submodules 'super/sub'
and 'super/sub1'. 'super/sub' itself contains a submodule
'super/sub/subsub'. Now suppose I run, from within 'super':

    echo hi >sub/subsub/stray-file
    echo hi >sub1/stray-file

Currently we get would see the following output in git-status:

    git status --short
     m sub
     ? sub1

With this patch applied, the untracked file in the nested submodule is
displayed as an untracked file on the 'super' level as well.

    git status --short
     ? sub
     ? sub1

This doesn't change the output of 'git status --porcelain=1' for nested
submodules, because its output is always ' M' for either untracked files
or local modifications no matter the nesting level of the submodule.

'git status --porcelain=2' is affected by this change in a nested
submodule, though. Without this patch it would report the direct submodule
as modified and having no untracked files. With this patch it would report
untracked files. Chalk this up as a bug fix.

This bug fix also affects the default output (non-short, non-porcelain)
of git-status, which is not tested here.

dd6962dd73 short status: improve reporting for submodule changes
If I add an untracked file to a submodule or modify a tracked file,
currently "git status --short" treats the change in the same way as
changes to the current HEAD of the submodule:

        $ git clone --quiet --recurse-submodules https://gerrit.googlesource.com/gerrit
        $ echo hello >gerrit/plugins/replication/stray-file
        $ sed -i -e 's/.*//' gerrit/plugins/replication/.mailmap
        $ git -C gerrit status --short
         M plugins/replication

This is by analogy with ordinary files, where "M" represents a change
that has not been added yet to the index.  But this change cannot be
added to the index without entering the submodule, "git add"-ing it,
and running "git commit", so the analogy is counterproductive.

Introduce new status letters " ?" and " m" for this.  These are similar
to the existing "??" and " M" but mean that the submodule (not the
parent project) has new untracked files and modified files, respectively.
The user can use "git add" and "git commit" from within the submodule to
add them.

Changes to the submodule's HEAD commit can be recorded in the index with
a plain "git add -u" and are shown with " M", like today.

To avoid excessive clutter, show at most one of " ?", " m", and " M" for
the submodule.  They represent increasing levels of change --- the last
one that applies is shown (e.g., " m" if there are both modified files
and untracked files in the submodule, or " M" if the submodule's HEAD
has been modified and it has untracked files).

While making these changes, we need to make sure to not break porcelain
level 1, which shares code with "status --short".  We only change
"git status --short".

Non-short "git status" and "git status --porcelain=2" already handle
these cases by showing more detail:

        $ git -C gerrit status --porcelain=2
        1 .M S.MU 160000 160000 160000 305c864db28eb0c77c8499bc04c87de3f849cf3c 305c864db28eb0c77c8499bc04c87de3f849cf3c plugins/replication
        $ git -C gerrit status
[...]
        modified:   plugins/replication (modified content, untracked content)

Scripts caring about these distinctions should use --porcelain=2.

244ea1b5e4 rev-parse: match @{upstream}, @{u} and @{push} case-insensitively
Change the revision parsing logic to match @{upstream}, @{u} & @{push}
case-insensitively.

Before this change supplying anything except the lower-case forms
emits an "unknown revision or path not in the working tree"
error. This change makes upper-case & mixed-case versions equivalent
to the lower-case versions.

The use-case for this is being able to hold the shift key down while
typing @{u} on certain keyboard layouts, which makes the sequence
easier to type, and reduces cases where git throws an error at the
user where it could do what he means instead.

These suffixes now join various other suffixes & special syntax
documented in gitrevisions(7) that matches case-insensitively. A table
showing the status of the various forms documented there before &
after this patch is shown below. The key for the table is:

 - CI  = Case Insensitive
 - CIP = Case Insensitive Possible (without ambiguities)
 - AG  = Accepts Garbage (.e.g. @{./.4.minutes./.})

Before this change:

    |----------------+-----+------+-----|
    | What?          | CI? | CIP? | AG? |
    |----------------+-----+------+-----|
    | @{<date>}      | Y   | Y    | Y   |
    | @{upstream}    | N   | Y    | N   |
    | @{push}        | N   | Y    | N   |
    |----------------+-----+------+-----|

After it:

    |----------------+-----+------+-----|
    | What?          | CI? | CIP? | AG? |
    |----------------+-----+------+-----|
    | @{<date>}      | Y   | Y    | Y   |
    | @{upstream}    | Y   | Y    | N   |
    | @{push}        | Y   | Y    | N   |
    |----------------+-----+------+-----|

The ^{<type>} suffix is not made case-insensitive, because other
places that take <type> like "cat-file -t <type>" do want them case
sensitively (after all we never declared that type names are case
insensitive). Allowing case-insensitive typename only with this syntax
will make the resulting Git as a whole inconsistent.

This change was independently authored to scratch a longtime itch, but
when I was about to submit it I discovered that a similar patch had
been submitted unsuccessfully before by Conrad Irwin in August 2011 as
"rev-parse: Allow @{U} as a synonym for
@{u}" (<1313287071-7851-1-git-send-email-conrad.irwin@gmail.com>).

The tests for this patch are more exhaustive than in the 2011
submission. The starting point for them was to first change the code
to only support upper-case versions of the existing words, seeing what
broke, and amending the breaking tests to check upper case & mixed
case as appropriate, and where not redundant to other similar
tests. The implementation itself is equivalent.

783b829287 ref-filter: reflow recently changed branch/tag/for-each-ref docs
Reflow the recently changed branch/tag-for-each-ref
documentation. This change shows no changes under --word-diff, except
the innocuous change of moving git-tag.txt's "[--sort=<key>]" around
slightly.

ac3f5a3468 ref-filter: add --no-contains option to tag/branch/for-each-ref
Change the tag, branch & for-each-ref commands to have a --no-contains
option in addition to their longstanding --contains options.

This allows for finding the last-good rollout tag given a known-bad
<commit>. Given a hypothetically bad commit cf5c7253e0, the git
version to revert to can be found with this hacky two-liner:

    (git tag -l 'v[0-9]*'; git tag -l --contains cf5c7253e0 'v[0-9]*') |
        sort | uniq -c | grep -E '^ *1 ' | awk '{print $2}' | tail -n 10

With this new --no-contains option the same can be achieved with:

    git tag -l --no-contains cf5c7253e0 'v[0-9]*' | sort | tail -n 10

As the filtering machinery is shared between the tag, branch &
for-each-ref commands, implement this for those commands too. A
practical use for this with "branch" is e.g. finding branches which
were branched off between v2.8.0 and v2.10.0:

    git branch --contains v2.8.0 --no-contains v2.10.0

The "describe" command also has a --contains option, but its semantics
are unrelated to what tag/branch/for-each-ref use --contains for. A
--no-contains option for "describe" wouldn't make any sense, other
than being exactly equivalent to not supplying --contains at all,
which would be confusing at best.

Add a --without option to "tag" as an alias for --no-contains, for
consistency with --with and --contains.  The --with option is
undocumented, and possibly the only user of it is
Junio (<xmqqefy71iej.fsf@gitster.mtv.corp.google.com>). But it's
trivial to support, so let's do that.

The additions to the the test suite are inverse copies of the
corresponding --contains tests. With this change --no-contains for
tag, branch & for-each-ref is just as well tested as the existing
--contains option.

In addition to those tests, add a test for "tag" which asserts that
--no-contains won't find tree/blob tags, which is slightly
unintuitive, but consistent with how --contains works & is documented.

1e0c3b680c tag: change --point-at to default to HEAD
Change the --points-at option to default to HEAD for consistency with
its siblings --contains, --merged etc. which default to
HEAD. Previously we'd get:

    $ git tag --points-at 2>&1 | head -n 1
    error: option `points-at' requires a value

This changes behavior added in commit ae7706b9ac (tag: add --points-at
list option, 2012-02-08).

6a338149f6 tag: implicitly supply --list given another list-like option
Change the "tag" command to implicitly turn on its --list mode when
provided with a list-like option such as --contains, --points-at etc.

This is for consistency with how "branch" works. When "branch" is
given a list-like option, such as --contains, it implicitly provides
--list. Before this change "tag" would error out on those sorts of
invocations. I.e. while both of these worked for "branch":

    git branch --contains v2.8.0 <pattern>
    git branch --list --contains v2.8.0 <pattern>

Only the latter form worked for "tag":

    git tag --contains v2.8.0 '*rc*'
    git tag --list --contains v2.8.0 '*rc*'

Now "tag", like "branch", will implicitly supply --list when a
list-like option is provided, and no other conflicting non-list
options (such as -d) are present on the command-line.

Spelunking through the history via:

    git log --reverse -p -G'only allowed with' -- '*builtin*tag*c'

Reveals that there was no good reason for not allowing this in the
first place. The --contains option added in 32c35cfb1e ("git-tag: Add
--contains option", 2009-01-26) made this an error. All the other
subsequent list-like options that were added copied its pattern of
making this usage an error.

The only tests that break as a result of this change are tests that
were explicitly checking that this "branch-like" usage wasn't
permitted. Change those failing tests to check that this invocation
mode is permitted, add extra tests for the list-like options we
weren't testing, and tests to ensure that e.g. we don't toggle the
list mode in the presence of other conflicting non-list options.

With this change errors messages such as "--contains option is only
allowed with -l" don't make sense anymore, since options like
--contain turn on -l. Instead we error out when list-like options such
as --contain are used in conjunction with conflicting options such as
-d or -v.

c485b24c42 tag: change misleading --list <pattern> documentation
Change the documentation for --list so that it's described as a
toggle, not as an option that takes a <pattern> as an argument.

Junio initially documented this in b867c7c23a ("git-tag: -l to list
tags (usability).", 2006-02-17), but later Jeff King changed "tag" to
accept multiple patterns in 588d0e834b ("tag: accept multiple patterns
for --list", 2011-06-20).

However, documenting this as "-l <pattern>" was never correct, as
these both worked before Jeff's change:

    git tag -l 'v*'
    git tag 'v*' -l

One would expect an option that was documented like that to only
accept:

    git tag --list
    git tag --list 'v*rc*'

And after Jeff's change, one that took multiple patterns:

    git tag --list 'v*rc*' --list '*2.8*'

But since it's actually a toggle all of these work as well, and
produce identical output to the last example above:

    git tag --list 'v*rc*' '*2.8*'
    git tag --list 'v*rc*' '*2.8*' --list --list --list
    git tag --list 'v*rc*' '*2.8*' --list -l --list -l --list

Now the documentation is more in tune with how the "branch" command
describes its --list option since commit cddd127b9a ("branch:
introduce --list option", 2011-08-28).

Change the test suite to assert that these invocations work for the
cases that weren't already being tested for.

75ec4a6cb0 branch doc: update description for --list
The paragraph begins with a sample command line `git branch <name>`
that has nothing to do with the option being described.  Remove it,
but use the space to instead show that multiple patterns can be
given.

Also mention the unfortunate `-l` that can be easily confused with
it.
