Hello, Apollo users of MUSH.

I have been told that several Apollo users are having problems with
MUSH.  I know of two problems with MUSH 6.4/6.5 (all patch levels).
I have fixes for both.

Problem #1:

   Suppose you are running MUSH in Curses mode and iconify the pad
   in which MUSH is executing.  Suppose you then logout.  You will
   find that the DM can't kill the MUSH process :-( .  Apply this
   fix (by hand) to the function cleanup() in file signals.c:

   Old code fragment:

      #ifdef CURSES
          if (iscurses)
              iscurses = FALSE, endwin();
      #endif /* CURSES */

   New code fragment:

      #ifdef CURSES
          if (iscurses)
          {
            iscurses = FALSE;
            if (sig != SIGHUP)
                endwin();
          }
      #endif /* CURSES */
    
   Notes:

   a) This is not a MUSH problem, this is an Apollo problem.
   b) Make sure the preprocessor directives (#ifdef and #endif)
      begin in column 1!
   c) Bart and Dan may add a patch similar to this to MUSH (they're
      still discussing its merits), so make a copy of the original
      signals.c and save it _before_ applying this fix so that you
      can later patch with their future mods.

Problem #2:

   If you use MUSH in Shell mode, you will find that interrupts
   (^C/^Q) don't work.  This is a big pain if you want to blow
   away a message that you're composing.  To work around this
   problem, invoke MUSH thusly:

      mush -e -S

   The "-e" switch tells MUSH to not run in cbreak mode.  In
   non-cbreak mode, you will find that editing messages via
   ~t, ~s, etc. has changed.  You will _not_ be prompted with
   the old contents of the header.  Instead, you must completely
   retype the header.  So it's a tradeoff.  Which feature do
   you want most in Shell mode?
