Subject: wildmatch: follow Git's coding convention
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=327f2f3ebb2310653e78244293f6f34b28571142;p=git.git

wildmatch: follow Git's coding convention

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"
