There are a handful of places where we call check_refname_format() on a
substring after "refs/" of a refname we are going to use, and filter out a
valid match with "refs/stash" with such a pathspec. Not sending a stash
may arguably be a feature (as stash is inherently a local workflow
element), but the code in the transport layer is oblivious to this
filtering performed by the lower layer of the code, and complains that the
other side did not send all the objects that needs to complete refs/stash
at the end, even though the code will not write refs/stash out anyway, and
making the whole command fail.
This is an attempt to "fix" it by using check_refname_format() on the
whole "refs/....." string and allowing refs/stash to be also copied.

* With this patch:
$ git checkout HEAD^0 ;# make sure we are on detached HEAD
$ git fetch $somewhere +refs/*:refs/*
and
victim$ git config receive.denyCurrentBranch warn
master$ git push victim +refs/*:refs/*
should work.
