Ok, after testing it, some changes needed to be made and so they were
made. Now it works (at least for me it worked).
This is just an idea, but wouldn't it be interesting if we used the
stat_busy, stat_done, and stat_fail stuff from /etc/rc.d/functions for
the messages in pacman-optimize?
Anyway, here is the patch for FS #5009 (woops, just caught another
bug.........it wouldn't be able to work after a successful one but it
would work after the failure ('cause pacman.new was still haning
around.........fixed). It is below as usual.
