Long ago, 47c9739e replaced the shell quoting in git-am with "git
rev-parse --sq-quote" (instead of sed). Maybe we can do the same for
get_author_ident_from_commit (though it is a little trickier there, as
we are also parsing values directly out of --pretty=raw).

It would be nice if the --pretty format placeholders had a "shell-quote"
modifier, and we could just do:

  git show --format='GIT_AUTHOR_NAME=%(an:shell)'

or something similar. for-each-ref knows about shell-quoting, but we
can't use it here, because we are looking at arbitrary commits, not just
ones pointed to by refs.
