[PATCH v2 4/9] mailmap: do not downcase mailmap entries

From
Eric Sunshine <sunshine@sunshineco.com>
Date

Message-ID
<1373871253-96480-5-git-send-email-sunshine@sunshineco.com>
In-Reply-To

From: Junio C Hamano <gitster@pobox.com>

The email addresses in the records read from the .mailmap file are downcased very early, and then used to match against e-mail addresses in the input. Because we do use case insensitive version of string list to manage these entries, there is no need to do this, and worse yet, downcasing the rewritten/canonical e-mail read from the .mailmap file loses information.

Stop doing that, and also make the string list used to keep multiple names for an mailmap entry case insensitive (the code that uses the list, lookup_prefix(), expects a case insensitive match).
