| Gurgle.  Don't even joke about it...  I've had a couple of brushes with
| xterm code, and it's pretty scary.  It wouldn't take a few moves, it
\ would take fairly massive lobotomies all around...

  My Mama didn't raise no fool.  Why do you think I didn't volunteer? :-)
But, really widgetizing the VT100 and TEK code would be The Right Thing
To Do ...  And, after all, xterm does have the system independent pty
code already, so that wouldn't have to be done over.  It would just have
to be pulled out into a separate set of helper routines.  And making the
pty routines available for all to use would also be The Right Thing To Do.

| Another option would be to require that the editor named by *Editor do
| its own windows.  Then, supply a command called xvi, which for now is a
| program (shell script, probably) that executes vi in an xterm window with
| appropriate signals ignored, scrollbars forced off, and with the title
| bar set correctly (we used this as a hack to make a System V program
| called cscope bring up editor windows instead of editing in the current
\ window).  Later, when a real xvi is available, it can replace this.

  I didn't suggest this because I didn't want require the overhead of
starting up another X client which is pretty high compared to an already
existing client simply starting up a new window.  But you're right, it's
a very simple approach and the one that xrn took.  If I use emacs, my
editor command is just something like ``emacs %f'' (sorry if I have the
% escape codes wrong here -- it's been a while since I looked at xrn).
If I use vi, my editor command is something like ``xterm -e jove %f''.
It works very well if a bit slowly.
