I agree it is probably not worth creating an option for.  It is
probably best to just decide to wrap or not to wrap... "that is the
question"  ;-)

I'm working on a graphical menu system for the Google Summer of Code
2008.  You can find out more about it at:

It's not in the GRUB codebase yet, but it under heavy development.

I'm fine with either option -- I'll just make it consistent with
whatever the core GRUB developers agree on.
