The user can be presented with invalid completion results
when trying to complete a 'git checkout' command. This can happen
when using a branch name prefix that matches multiple remote branches.
For example, if available branches are:
master
remotes/GitHub/maint
remotes/GitHub/master
remotes/origin/maint
remotes/origin/master
When performing completion on 'git checkout ma' the user will be
given the choices:
maint
master
However, 'git checkout maint' will fail in this case, although
completion previously said 'maint' was valid. Furthermore, when
performing completion on 'git checkout mai', no choices will be
suggested. So, the user is first told that the branch name
'maint' is valid, but when trying to complete 'mai' into 'maint',
that completion is no longer valid.
The completion results should never propose 'maint' as a valid
branch name, since 'git checkout' will refuse it.
The reason for this bug is that the uniq program only
works with sorted input. The man page states
"uniq prints the unique lines in a sorted file".
When __git_refs uses the guess heuristic employed by checkout for
tracking branches it wants to consider remote branches but only if
the branch name is unique. To do that, it calls 'uniq -u'. However
the input given to 'uniq -u' is not sorted.
Therefore, in the above example, when dealing with 'git checkout ma',
"__git_refs '' 1" will find the following list:
master
maint
master
maint
master
which, when passed to 'uniq -u' will remain the same. Therefore
'maint' will be wrongly suggested as a valid option.
When dealing with 'git checkout mai', the list will be:
maint
maint
which happens to be sorted and will be emptied by 'uniq -u',
properly ignoring 'maint'.
A solution for preventing the completion script from suggesting
such invalid branch names is to first call 'sort' and then 'uniq -u'.

The current tcsh-completion support for Git, as can be found on the
Internet, takes the approach of defining the possible completions
explicitly. This has the obvious draw-back to require constant
updating as the Git code base evolves.
The approach taken by this commit is to to re-use the advanced bash
completion script and use its result for tcsh completion. This is
achieved by sourcing the bash script and outputting the completion
result for tcsh consumption.
Three solutions were looked at to implement this approach with (C)
being retained:
A) Modifications:
git-completion.bash and new git-completion.tcsh
Modify the existing git-completion.bash script to support
being sourced using bash (as now), but also executed using bash.
When being executed, the script will output the result of the
computed completion to be re-used elsewhere (e.g., in tcsh).
The modification to git-completion.bash is made not to be
tcsh-specific, but to allow future users to also re-use its
output. Therefore, to be general, git-completion.bash accepts a
second optional parameter, which is not used by tcsh, but could
prove useful for other users.
Pros:
1- allows the git-completion.bash script to easily be re-used
2- tcsh support is mostly isolated in git-completion.tcsh
Cons (for tcsh users only):
1- requires the user to copy both git-completion.tcsh and
git-completion.bash to ${HOME}
2- requires bash script to have a fixed name and location:
${HOME}/.git-completion.bash
B) Modifications:
git-completion.bash
Modify the existing git-completion.bash script to support
being sourced using bash (as now), but also executed using bash,
and sourced using tcsh.
Pros:
1- only requires the user to deal with a single file
2- maintenance more obvious for tcsh since it is entirely part
of the same git-completion.bash script.
Cons:
1- tcsh support could affect bash support as they share the
same script
2- small tcsh section must use syntax suitable for both tcsh
and bash and must be at the beginning of the script
3- requires script to have a fixed name and location:
${HOME}/.git-completion.sh (for tcsh users only)
C) Modifications:
New git-completion.tcsh
Provide a short tcsh script that generates another script
which extends git-completion.bash. This new script can be
used by tcsh to perform completion.
Pros:
1- tcsh support is entirely isolated in git-completion.tcsh
2- new tcsh script can be as complex as needed
Cons (for tcsh users only):
1- requires the user to copy both git-completion.tcsh and
git-completion.bash to ${HOME}
2- requires bash script to have a fixed name and location:
${HOME}/.git-completion.bash
3- sourcing the new script will generate a third script
Approach (C) was selected avoid any modification to git-completion.bash.

config: don't segfault when given --path with a missing value
When given a variable without a value, such as '[section] var' and
asking git-config to treat it as a path, git_config_pathname returns
an error and doesn't modify its output parameter. show_config assumes
that the call is always successful and sets a variable to indicate
that vptr should be freed. In case of an error however, trying to do
this will cause the program to be killed, as it's pointing to memory
in the stack.
Detect the error and return immediately to avoid freeing or accessing
the uninitialed memory in the stack.

When we switch to a new branch using checkout, we usually output a

The reason is that the unborn branch is a special case (see abe1998),
and does not follow the usual switch_branches code path. Let's add a
similar informational message to the special case to match the usual
code path.

Update cygwin.c for new mingw-64 win32 api headers
The cygwin project recently switched to a new implementation of the
windows api, now using header files from the mingw-64 project. These
new header files are incompatible with the way cygwin.c included the
old headers: cygwin.c can be compiled using the new or the older (mingw)
headers, but different files must be included in different order for each
to work. The new headers are in use only for the current release series
(based upon the v1.7.x dll version). The previous release series using
the v1.5 dll is kept available but unmaintained for use on older versions
of Windows. So, patch cygwin.c to use the new include ordering only if
the dll version is 1.7 or higher.

When commit 592ea41 refactored the list of extensions for

bash, ksh, zsh, and sh should all map to sh since they share
similar syntax, but we ended up just mapping "bash" to
"bash" and so forth).
