Tolerating empty path components in ref names means each ref does
not have a unique name. This creates difficulty for porcelains
that want to see if two branches are equal. Add a helper associating
to each ref a canonical name.
If a user asks a porcelain to create a ref "refs/heads//master",
the porcelain can run "git check-ref-format --print refs/heads//master"
and only deal with "refs/heads/master" from then on.

Before the --, always attempt ref completion. This helps with
entering the <treeish> arguments to git-grep. As a bonus, you can
work around git-grep's current lack of --all by hitting M-*, ugly as
the resulting command line may be.
Strictly speaking, completing the regular expression argument (or
option argument) makes no sense. However, we cannot prevent _all_
completion (it will fall back to filenames), so we dispense with any
additional complication to detect whether the user still has to enter
a regular expression.

In all parts of git, .gitignore and other exclude files
impact only how we treat untracked files; they should have
no effect on files listed in the index.
This behavior was originally implemented very early on in
9ff768e, but only for --exclude-from. Later, commit 63d285c
accidentally caused us to trigger the behavior for
--exclude-per-directory.
This patch totally ignores excludes for files found in the
index. This means we are reversing the original intent of
9ff768e, while at the same time fixing the accidental
behavior of 63d285c. This is a good thing, though, as the
way that 9ff768e behaved does not really make sense with the
way exclusions are used in modern git.

When saying the initial branch is equal to the currently active
remote branch, it is probably intended that the branch heads
point to the same commit. Maybe it would be more useful to a
new user to emphasize that the tree contents and history are the
same.
More important, probably, is that this new branch is set up so
that "git pull" merges changes from the corresponding remote
branch. The next paragraph addresses that directly. What the
reader needs to know to begin with is that (1) the initial branch
is your own; if you do not pull, it won't get updated, and that
(2) the initial branch starts out at the same commit as the
upstream.

Aliases with newlines have been a problem since commit 56fc25f (Bash
completion support for remotes in .git/config., 2006-11-05). The chance
of the problem occurring has been slim at best, until commit 518ef8f
(completion: Replace config --list with --get-regexp, 2009-09-11)
removed the case statement introduced by commit 56fc25f. Before removing
the case statement, most aliases with newlines would work unless they
were specially crafted as follows
[alias]
foo = "log -1 --pretty='format:%s\nalias.error=broken'"
After removing the case statement, a more benign alias like
[alias]
whowhat = "log -1 --pretty='format:%an <%ae>\n%s'"
wont-complete = ...
would cause the completion to break badly.
For now, revert the removal of the case statement until someone comes up
with a better way to get keys from git-config.

After commit 511a3fc (wrap git's main usage string., 2009-09-12), the
bash completion for git commands includes COMMAND and [ARGS] when it
shouldn't. Fix this by grepping more strictly for a line with git
commands. It's doubtful whether git will ever have commands starting
with anything besides numbers and letters so this should be fine. At
least by being stricter we'll know when we break the completion earlier.

a branch from a remote-tracking branch, a tag, or an interesting

There are several reasons a git-pull invocation might not
have anything marked for merge:
1. We're not on a branch, so there is no branch
configuration.
2. We're on a branch, but there is no configuration for
this branch.
3. We fetched from the configured remote, but the
configured branch to merge didn't get fetched (either
it doesn't exist, or wasn't part of the fetch refspec).
4. We fetched from the non-default remote, but didn't
specify a branch to merge. We can't use the configured
one because it applies to the default remote.
5. We fetched from a specified remote, and a refspec was
given, but it ended up not fetching anything (this is
actually hard to do; if the refspec points to a remote
branch and it doesn't exist, then fetch will fail and
we never make it to this code path. But if you provide
a wildcard refspec like
refs/bogus/*:refs/remotes/origin/*
then you can see this failure).
We have handled (1) and (2) for some time. Recently, commit
a6dbf88 added code to handle case (3).
This patch handles cases (4) and (5), which previously just
fell under other cases, producing a confusing message.
While we're at it, let's rewrap the text for case (3), which
looks terribly ugly as it is.

When git is compiled with the MIPSpro 7.4.4m compiler, and NO_PTHREADS is
set, and NO_MMAP is _not_ set, then git segfaults when trying to access the
first entry in a reflog. If NO_PTHREADS is not set (which implies that the
pthread library is linked in), or NO_MMAP _is_ set, then the segfault is
not encountered. The conservative choice has been made to set NO_MMAP in
the Makefile to avoid this flaw. The GNU C compiler does not produce this
behavior.
The segfault happens in refs.c:read_ref_at(). The mmap succeeds, and the
loop is executed properly until rec is rewound into the first line (reflog
entry) of the file. The segfault is caught by test 28 of
t1400-update-ref.sh which fails when 'git rev-parse --verify "master@{May 25
2005}"' is called.
So, add a comment in the Makefile to describe why NO_MMAP is set and as a
hint to those who may be interested in unsetting it.

When ls-files was called with -i but no exclude pattern, it was
calling fprintf(stderr, "...", NULL) and then exiting. On Solaris,
passing NULL into fprintf was causing a segfault. On glibc systems,
it was simply producing incorrect output (eg: "(null)": ...). The
NULL pointer was a result of argv[0] not being preserved by the option
parser. Instead of requesting that the option parser preserve
argv[0], use die() with a constant string.
A trigger for this bug was: `git ls-files -i`

During an MSVC build on cygwin, the make program did not notice
when the compiler or linker exited with an error. This was caused
by the scripts exiting with the value returned by system() directly.
On POSIX-like systems, such as cygwin, the return value of system()
has the exit code of the executed command encoded in the first byte
(ie the value is shifted up by 8 bits). This allows the bottom
7 bits to contain the signal number of a terminated process, while
the eighth bit indicates whether a core-dump was produced. (A value
of -1 indicates that the command failed to execute.)
The make program, however, expects the exit code to be encoded in the
bottom byte. Futhermore, it apparently masks off and ignores anything
in the upper bytes.
However, these scripts are (naturally) intended to be used on the
windows platform, where we can not assume POSIX-like semantics from
a perl implementation (eg ActiveState). So, in general, we can not
assume that shifting the return value right by eight will get us
the exit code.
In order to improve portability, we assume that a zero return from
system() indicates success, whereas anything else indicates failure.
Since we don't need to know the exact exit code from the compiler
or linker, we simply exit with 0 (success) or 1 (failure).

In the MSVC section of the Makefile, BASIC_CFLAGS is set to a
value which contains the string "-DWIN32-D_CONSOLE". This results
in a (single) malformed -Define being passed to the compiler.
At least on my cygwin installation, the msvc compiler seems to
ignore this parameter, without issuing an error or warning, and
results in the WIN32 and _CONSOLE macros being undefined. This
breaks the build.
In order to fix the build, we simply insert a space between the
two -Define parameters, "-DWIN32" and "-D_CONSOLE", as originally
intended.
