Subject: [PATCHv5 2/2] bash-completion: Fix __git_ps1 to work with "set -u"

From: Andrew Sayers <[email-masked]>
Date: Thu, 17 Jun 2010 22:32:16 +0100

Define several variables in __git_ps1 to avoid errors under "set -u" semantics.

__git_ps1 seems to have been missed when the rest of the file was fixed in
25a31f8.
