Hi!

Please find Completion/Unix/_emacs attached.

Note that I’ve been lazy and haven’t implemented _emacs_color, instead
using _x_color.  It’s not worth the effort for me, as I never use any
of the color options, but if someone wants a challenge, perhaps
execute emacs in batch mode and run list-colors-display or some such.

Also note that I haven’t implemented +number and +line:column.  It
shouldn’t be hard to do, but I couldn’t figure out how to do it
properly, so I left it alone.
