This patch adds a unique identifier for each file shown by "git status".
Subsequent operation (add/rm/checkout/commit/reset) may use these ids
to simplify specifying the files, provided that they are taught about
the --id option as well.
Example:
$ git status --id
# On branch local
# Changed but not updated:
# (use "git add <file>..." to update what will be committed)
# (use "git checkout -- <file>..." to discard changes in working directory)
#
# modified: builtin-add.c (m1)
# modified: builtin-checkout.c (m2)
# modified: builtin-commit.c (m3)
# modified: builtin-reset.c (m4)
# modified: builtin-rm.c (m5)
#
# Untracked files:
# (use "git add <file>..." to include in what will be committed)
#
# makefile.debug (x1)
# nazri.sh (x2)
no changes added to commit (use "git add" and/or "git commit -a")
$ git add --id m1
# Short for "git add builtin-add.c
$ git add --id m3,m5
# Short for "git add builtin-commit.c builtin-rm.c"
# Even shorter: -d is equivalent to --id
$ git add -d m3,m5
