Don't export $PROMPT. Child processes do not need to know about it and
it causes more harm than it does good.

Well, grml's zshrc does a lot of stuff already. And it uses vcs_info,
too. It also has a precmd() function of its own.

There is potentially more than one way to achieve what you want.

The easiest is probably to change the precmd() function and the PS1=
definition in grml's zsh setup to your liking. That would make
upgrading later a little hairier, though. You could also overwrite
precmd() and PS1= in your user specific file. But note, that grml's
precmd() may already do things you want to keep so copy code for that
stuff over into your file.

If your questions are really about grml's *specific* setup, then
there's a user mailing list for the project and an IRC channel named
#grml on freenode. Those places may be more suited.
