decapitalization

[Leigh L. Klotz <KLOTZ@MIT-OZ>]

Probably what's happening is the following
  You exit EMACS whith ^X-^C.
   Control returns to the exec immediately on the ^C, leaving
   EMACS with a ^X pending.
  You return to EMACS and type ^L to redisplay the screen.
   EMACS performs ^X-^L (Lowercase Region).

You can avoid this by exiting EMACS with Z-^Z.  Note that you'll
get the same problem on ITS if you exit with ^X-^Z, which is a
"clean exit" command on TOPS-20.  I prefer to exit via ^Z-^Z, which
is a "clean exit" command on TOPS-20, and just does two ^Z's on ITS.
