???  Can you tell me why groff should handle passwords?  We are
talking about displaying documents in the viewer, aren't we?  If mc
has to display a password, simply don't use color escapes.

There are three possibilities to reactivate the old behaviour:

   1) Setting an environment variable GROFF_NO_SGR.
   2) Passing the -c option to grotty (i.e. adding `-P-c' to groff).
   3) Add the special \X'tty:sgr 1' to the document.

I recommend 2).
