Can you tell me just what options/key sequences you are using to start
mc?  I've just started mc in a console and I get a '$ ' for a prompt in
mc.  I have a minimal zsh env setup for this test and no ~/.inputrc.

This is interesting.  In a previous version of mc this worked (sort of),
but only if PS1 and RPROMPT were set in .zshenv (or one of the other
commonly sources zsh files).  With the latest mc-4.6.0-2 I see just a '$'
no matter what I set where.  I get the '$ ' running mc in rxvt too.
