Thanks a lot for these patches! The first two are perfectly okay, and
the third one looks good, with a minor nit: it's not a good idea to
hardcode foreground colors in the monitor itself:

we should left those to the template.

I've moved xmobar's source to git (http://github.com/jaor/xmobar), and
the git repo is a bit ahead of the old darcs one, but i think i'll have
little problem in adapting your patches (unless you prefer to do that
yourself, which would be great :)). Once that's done, i will try them
and, eventually, make them official in a new release.

Thanks again, and sorry for the repo inconveniences!

Cheers,
jao
