Subject: [PATCH 2/2] Speed up is_git_command() by checking early for internal commands
Date: Mon, 30 Dec 2013 22:07:38 +0100 [thread overview]
Message-ID: <52C1E09A.8040907@gmail.com> (raw)
In-Reply-To: <52C1E028.8000004@gmail.com>
Since 2dce956 is_git_command() was a bit slow as it does file I/O in the
call to list_commands_in_dir(). Avoid the file I/O by adding an early
check for internal commands.
