apply --recount: allow "no-op hunks"
When editing patches e.g. in `git add -e`, it is quite common that a
hunk ends up having no -/+ lines, i.e. it is now supposed to do nothing.
This use case was broken by ad6e8ed37bc1 (apply: reject a hunk that does
not do anything, 2015-06-01) with the good intention of catching a very
real, different issue in hand-edited patches.
So let's use the `--recount` option as the tell-tale whether the user
would actually be okay with no-op hunks.
Add a test case to make sure that this use case does not regress again.
