This is broken in pcmode due to a Bash bug. The command:
printf -v foo "" asdf
is a no-op in Bash. The variable foo is never changed in any way --
it is neither unset nor set to the empty string.
Also, I noticed that I get an error message if I cd into .git:
fatal: This operation must be run in a work tree
I think the following change will fix the above issues, and it has the
advantage of avoiding unnecessary work if the directory is ignored:
diff --git a/contrib/completion/git-prompt.sh b/contrib/completion/git-prompt.sh

It would be good to add additional test cases for pcmode (two or three
arguments to __git_ps1) and 'cd .git' so that the above issues don't
reappear.
Thanks,
