I think that there is no need to make this backend-specific. What we're
testing here is that `git stash drop` is able to drop the latest reflog
entry. The calls to cut(1) are only used to verify that the contents of
the reflog entry look as expected while only verifying the old and new
object IDs.

So how about below patch to make it generic instead?
