[pacman-dev] [PATCH] Add 'compress' compression format as an available option

[Dan McGee]

This adds the '.tar.Z' option to both repo-add and makepkg for no other
reason than "why not", and because bsdtar supports it natively with the
'-Z' flag. Also update the documentation accordingly.

This is about as random as it gets. Did notice we lack some consistency in our
doc/ directory regarding extension quoting, as you can see the two different
styles below (and a third in use elsewhere).
