From e018670607ce6491163fbefb8eb84eec8588bf7b Mon Sep 17 00:00:00 2001 From: Lukas Fleischer Date: Fri, 30 May 2014 09:32:48 +0200 Subject: Accept upper case letters in valid_username() In commit 0722f46 (Simplify valid_user() and valid_username(), 2014-02-06), the conversion to lower case letters was unintentionally removed and in consequence, names with upper case letters have been rejected since then. Instead of reintroducing the conversion, add the "i" modifier to the regular expression validating the name to do case-insensitive pattern matching.
