Subject: [PATCH v2 3/5] compat/wildmatch: fix case-insensitive matching

From: Nguyễn Thái Ngọc Duy <[email-masked]>
Date: Sun, 16 Sep 2012 22:27:43 +0700

dowild() does case insensitive matching by lower-casing the text. That
means lower case letters in patterns imply case-insensitive matching,
but upper case means exact matching.

We do not want that subtlety. Lower case pattern too so iwildmatch()
always does what we expect it to do.
