      We have a problem with the VAX VMS Emacs version EMACS.EXE;73.
 If we invoke an emacs as a subprocess from a terminal with a 5 character
 name, such as PTA10: pause-emacs doesn't drop back to the top level process;
 it just redraws the screen. Maybe the register definition of ttyname
 has something to do with this (loses fifth char?)
    Extract from EMACS.C
   --------------------
 static  LockTty () {		/* Try to set the per-tty lock.  If we
 				   fail, exit back to Unix with a
 				   message. */
     register    fd;
     register char  *tt = (char *) ttyname (0);
     register char  *p;
     int     ExclusiveMode;
     for (p = tt; *p;)
 	if (*p++ == '/')
 	    tt = p;
     sprintfl (LockFile, sizeof LockFile, "/tmp/Emacs-%s", tt);
