[PATCH v4 1/2] builtin/remote: remove postfixcmp() and use suffixcmp() instead

[PATCH v4 1/2] builtin/remote: remove postfixcmp() and use suffixcmp() instead

[Christian Couder]

Commit 8cc5b290 (git merge -X<option>, 25 Nov 2009) introduced
suffixcmp() with nearly the same implementation as postfixcmp()
that already existed since commit 211c8968 (Make git-remote a
builtin, 29 Feb 2008).

The only difference between the two implementations is that,
when the string is smaller than the suffix, one implementation
returns 1 while the other one returns -1.

But, as postfixcmp() is only used to compare for equality, the
distinction does not matter and does not affect the correctness of
this patch.

As postfixcmp() has always been static in builtin/remote.c
and is used nowhere else, it makes more sense to remove it
and use suffixcmp() instead in builtin/remote.c, rather than
to remove suffixcmp().
