Subject: [PATCH 3/8] Integrate wildmatch to git

From: Nguyễn Thái Ngọc Duy <[email-masked]>
Date: Tue, 9 Oct 2012 10:09:02 +0700

This makes wildmatch.c part of libgit.a and builds test-wildmatch; the
dependency on libpopt in the original has been replaced with the use
of our parse-options. Global variables in test-wildmatch are marked
static to avoid sparse warnings.
