[PATCH 4/4] connect.c: drop path_match function

[Jeff King <peff@peff.net>]

This function was used for comparing local and remote ref
names during fetch (which makes it a candidate for "most
confusingly named function of the year").

It no longer has any callers, so let's get rid of it.

I just did the exact-string match inline in the previous patch. I could
also have modified path_match to do it. But really, I can't think of a
worse name for a global function in a system which is all about
managing content in paths. Unless, you know, it actually matched paths.
Which it doesn't.
