Unify the formatting of the --help switch for pacman utils, if it exists.
All of the pacman utils will now output help text using the following
format:
util-name (pacman) v<pacman version>
one line description of util's purpose
Usage: util-name [options]
-b, --bar whatever --bar does
-f, --foo whatever --foo does
-h, --help display this help message
