shallow: add repository argument to check_shallow_file_for_update

stefanbeller · gitster · commit 22bdc7c4ff28 · 2018-05-18T08:13:10.000+09:00
Add a repository argument to allow callers of check_shallow_file_for_update
to be more specific about which repository to handle. This is a small
mechanical change; it doesn't change the implementation to handle
repositories other than the_repository yet.

As with the previous commits, use a macro to catch callers passing a
repository other than the_repository at compile time.
