Subject: [PATCH v2 3/4] Speed up is_git_command() by checking early for internal commands
Date: Thu, 02 Jan 2014 17:17:11 +0100 [thread overview]
Message-ID: <52C59107.6080005@gmail.com> (raw)
In-Reply-To: <52C58FD7.6010608@gmail.com>
Since 2dce956 is_git_command() is 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.
