Shoot.  I tested the Linux text console, and it also happens there.  So I 
guess the problem is widespread enough that perhaps I really should put in 
some workaround code.  Initially I thought it was only a Solaris issue, but if 
even a current linux box in text mode shows the problem, I don't like it.

I'd love to know if the issue is a curses bug.  But in the meantime, I guess 
I'll neeed to wrap the curses code in a check, so they don't occur for any 
terminal type other than xterm.

Checking for TERM==xterm seems safe, since xterm, konsole and gnome-terminal 
all set TERM=xterm.  And this would leave other terminals, such as 
(linux,solaris,bsd)-text ok.

Does anyone see a downside to that (i.e., enabling curses ONLY if TERM=='xterm')?
