I have a git alias that takes a relative file name argument,
and would like to know from where in the tree it was invoked,
especially if inside a subdirectory of the git tree.
Consider .git/config:
[alias]
pwd = !/bin/pwd
Then a git tree:
/home/me
topdir/
.git/
subdir/
subdir-y.c
topdir-x.c
Then inside /home/me/topdir, all is well:
$ pwd
/home/me/topdir
$ git pwd
/home/me/topdir
But inside /home/me/topdir/subdir, the pwd alias is invoked in the wrong
dir:
$ pwd
/home/me/topdir/subdir
$ git pwd
/home/me/topdir
The implication of this is that I call an alias command like:
$ pwd
/home/me/topdir/subdir
$ git myalias subdir-y.c
myalias: No such file subdir-y.c
It looks like handle_alias() uses setup_git_directory_gently() to
find the .git, which chdir()s up until it gets there. Is there a
way to do this without changing the process current working
directory instead? I could even handle an environment variable
saving the original cwd, but that's ickier.
