Yes. I later noticed that subshell works when mc is launched
from sudo, so yes, it is a shell. Why csh is unsupported btw?
Is it docummented? Just checked, and found it in the FAQ.
But when I first had this problem half a year ago I didn't think
it could be dependant on the shell... It should probably be
added to the hints, so that new users have more chance to
notice it.
