Subject: [PATCH 05/13] wildmatch: follow Git's coding convention

From: Nguyễn Thái Ngọc Duy <[email-masked]>
Date: Mon, 15 Oct 2012 13:25:54 +0700

wildmatch's coding style is pretty close to Git's except the use of 4
space indentation instead of 8. This patch should produce empty diff
with "git diff -b"
