git-stash: remove untracked/ignored directories when stashed
The two new stash options --include-untracked and --all do not remove the
untracked and/or ignored files that are stashed if those files reside in
a subdirectory. e.g. the following sequence fails:
mkdir untracked &&
echo hello >untracked/file.txt &&
git stash --include-untracked &&
test ! -f untracked/file.txt
Within the git-stash script, git-clean is used to remove the
untracked/ignored files, but since the -d option was not supplied, it does
not remove directories.
So, add -d to the git-clean arguments, and update the tests to test this
functionality.
