Improve --help switch output for pacman utils
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 The --help switch does not exist for a couple of the utils, so the help/usage text for those will be displayed when the util is run with no arguments.
