Just noticed another issue here: it looks for a directory, though it  
should look for a file.

Oh, right, thanks.  I should have remembered, I wrote the test of the
prompt script for that case...
(On a related note: is it possible to have a '.git/rebase-apply'
directory, but neither 'rebasing' or 'applying' files within?  The
prompt script has a long if-elif chain with such a branch, and I
remember wondering how I could trigger it for testing.)

Anyway, so this could be something like (modulo likely whitespace damage):

diff --git a/contrib/completion/git-completion.bash
b/contrib/completion/git-completion.bash
index 07c34ef913..fac01d6985 100644
