Yes, but you don't get the credit.  It's been used before... :-p

Well, I've been reading some vim help.  A few interesting things surfaced.
For details, "help restorescreen", "help term", "help terminfo", and "help
xterm-screens" in vim.  FWIW, it works for me in an xterm, but doesn't in
the "bash window" (we *really* ought to come up with a better name for
that).  Looks like vim doesn't recognize TERM=cygwin and doesn't set t_ti
and t_te appropriately.  These two variables control the "alternate
screen" feature.  As they aren't even defined for TERM=cygwin, I don't
know how it ever worked (unless termcap/terminfo were changed recently).
