Sorry for being a bit unresponsive, got a lot on my plate these days.

Alright. I don't see were the variables with the colour escape sequences
are coming from. I'd lean towards not having coloured messages in these
utilities.

Well, we keep our code in separate git repositories. If you don't know
git yet, there's a free book only at: http://git-scm.com/book

We also keep some information about contributing to grml at:
http://grml.github.io/

The goal would be to create one email message per version control
commit. You can send those to grml-etc-core at grml.org or just attach them
to the issue you opened. Then git has some utilities to import them
again at my end with virtually no manual work at all.

I wrote about that work-flow a while back:
