This is complicated slightly by having to remember the previous -L range
for each file specified via -L<range>:file.
The existing implementation coalesces ranges for each file as each -L is
parsed which makes it impossible to refer back to the previous -L range
for any particular file. Re-implement to instead store each file's set
of -L ranges verbatim, and then coalesce the ranges in a post-processing
step.

Range specification -L/RE/ for blame/log unconditionally begins
searching at line one. Mailing list discussion [1] suggests that, in the
presence of multiple -L options, -L/RE/ should search relative to the
endpoint of the previous -L range, if any.
Teach the parsing machinery underlying blame's and log's -L options to
accept a start point for -L/RE/ searches. Follow-up patches will upgrade
blame and log to take advantage of this ability.

git-blame accepts only a single -L option or none. Clients requiring
blame information for multiple disjoint ranges are therefore forced
either to invoke git-blame multiple times, once for each range, or only
once with no -L option to cover the entire file, both of which can be
costly. Teach git-blame to accept multiple -L ranges. Overlapping and
out-of-order ranges are accepted.
In this patch, the X in -LX,Y is absolute (for instance, /RE/ patterns
search from line 1), and Y is relative to X. Follow-up patches provide
more flexibility over how X is anchored.

blame/log documentation describes -L option as:
-L<start>,<end>
-L:<regex>
<start> and <end> can take one of these forms:
* number
* /regex/
* +offset or -offset
* :regex
which is incorrect and confusing since :regex is not one of the valid
forms of <start> or <end>; in fact, it must be -L's lone argument.
Clarify by discussing :<regex> at the same indentation level as "<start>

Standard practice in Git documentation is for each variation of an
option (such as: -p / --porcelain) to be placed on its own line in the
OPTIONS table. The -L option does not follow suit. It cuddles "-L
<start>,<end>:<file>" and "-L :<regex>:<file>", separated by a comma.
This is inconsistent and potentially confusing since the comma
separating them is typeset the same as the comma in "<start>,<end>". Fix
this by placing each variation on its own line.

Currently using "git rm" on a submodule removes the submodule's work tree
from that of the superproject and the gitlink from the index. But the
submodule's section in .gitmodules is left untouched, which is a leftover
of the now removed submodule and might irritate users (as opposed to the
setting in .git/config, this must stay as a reminder that the user showed
interest in this submodule so it will be repopulated later when an older
commit is checked out).
Let "git rm" help the user by not only removing the submodule from the
work tree but by also removing the "submodule.<submodule name>" section
from the .gitmodules file and stage both. This doesn't happen when the
"--cached" option is used, as it would modify the work tree. This also
silently does nothing when no .gitmodules file is found and only issues a
warning when it doesn't have a section for this submodule. This is because
the user might just use plain gitlinks without the .gitmodules file or has
already removed the section by hand before issuing the "git rm" command
(in which case the warning reminds him that rm would have done that for
him). Only when .gitmodules is found and contains merge conflicts the rm
command will fail and tell the user to resolve the conflict before trying
again.
Also extend the man page to inform the user about this new feature. While
at it promote the submodule sub-section to a chapter as it made not much
sense under "REMOVING FILES THAT HAVE DISAPPEARED FROM THE FILESYSTEM".
In t7610 three uses of "git rm submod" had to be replaced with "git rm
--cached submod" because that test expects .gitmodules and the work tree
to stay untouched. Also in t7400 the tests for the remaining settings in
the .gitmodules file had to be changed to assert that these settings are
missing.

Using the same urlmatch_config_entry() infrastructure, add a new
mode "--get-urlmatch" to the "git config" command, to learn values
for the "virtual" two-level variables customized for the specific
URL.
git config [--<type>] --get-urlmatch <section>[.<key>] <url>
With <section>.<key> fully specified, the configuration data for
<section>.<urlpattern>.<key> for <urlpattern> that best matches the
given <url> is sought (and if not found, <section>.<key> is used)
and reported. For example, with this configuration:
[http]
sslVerify
[http "https://weak.example.com"]
cookieFile = /tmp/cookie.txt
sslVerify = false
You would get
$ git config --bool --get-urlmatch http.sslVerify https://good.example.com
true
$ git config --bool --get-urlmatch http.sslVerify https://weak.example.com
false
With only <section> specified, you can get a list of all variables
in the section with their values that apply to the given URL. E.g
$ git config --get-urlmatch http https://weak.example.com
http.cookiefile /tmp/cookie.txt
http.sslverify false

58960978 and 99780b0a added tests which demonstrated bugs (crashes) in
range-set and line-log when handed empty ranges specified via "log
-LX:file" where X is one greater than the last line of the file. After
these tests were added, it was realized that the ability to specify an
empty range is a loophole due to a bug in -L bounds checking. That bug
is slated to be fixed in a subsequent patch.
Unfortunately, the closure of this loophole makes it impossible to
continue checking range-set and line-log behavior with regard to empty
ranges since there is no other way to specify empty ranges via the
command-line. APIs of both facilities are private (file static) so
there likewise is no way to test their behaviors programmatically.
Consequently, retire these two tests.

start > EOF; 2010-02-08) attempted to rectify this shortcoming but has
its own off-by-one error which allows X to extend one line past end of

git blame -L5 foo # OK, blames line 5
git blame -L6 foo # accepted, no error, no output, huh?
git blame -L7 foo # error "fatal: file foo has only 5 lines"

In b04ba2bb4 Junio suggested to replace it with either

occurred often with the OPTION_BOOLEAN was a hidden boolean parameter.
So I defined OPT_HIDDEN_BOOL as an additional possible parse option
in parse-options.h to make life easy.
The OPT_HIDDEN_BOOL was used in checkout, clone, commit, show-ref.
The only exception, where there was need to fiddle with OPTION_SET_INT
was log and notes. However in these two files there is also a pattern,

Git commands write commit messages in UTF-8 by default, but that
default can be overridden by the [i18n] commitEncoding and
logOutputEncoding settings. With such a setting, the emails written
by the post-receive-email hook use a mixture of encodings:
1. Log messages use the configured log output encoding, which is
meant to be whatever encoding works best with local terminals
(and does not have much to do with what encoding should be used
for email)
2. Filenames are left as is: on Linux, usually UTF-8, and in the Mingw
port (which uses Unicode filesystem APIs), always UTF-8
3. The "This is an automated email" preface uses a project description
from .git/description, which is typically in UTF-8 to support
gitweb.
So (1) is configurable, and (2) and (3) are unconfigurable and
typically UTF-8. Override the log output encoding to always use UTF-8
when writing the email to get the best chance of a comprehensible
single-encoding email.
