Carl discovered a problem with UnDo.exe's method of establishing
XyWrite's ProcessID when launching from a LNK (cmd.exe)
Shortcut. Fixed.

Carl also pointed out that CAlled secondary copies of a file --
if you have a file open, you CAll it again, and you answer Y[es}
to the query "File is already open--open again?" -- are not
handled properly. Fixed.

I realized that Read-Only files must be skipped. Fixed.

Harry wonders whether "there will be problems with multiple
iterations
of Xy open at once." Correct, there will be problems. The
Timed ($T) method will almost certainly make a mess. You'd need
to Kill UnDo (KUD) in the first session before starting
the second session. Because closing either session will kill
all running iterations of UnDo.exe, you'd need to Restart UnDo
(RUD) in the remaining session IF that was the second
session. Too complicated! There is a potential for problems
with the Keystroke-Generated ($K) method too, related to
different content in [UNTITLED] windows with the same window
number. In short, I don't recommend doing it, period.
