    Sure, I'll volunteer a fix.  This is an amazingly simple one.  Don't
ask me how it got through, but one would suspect the wgetstr (or getstr)
aren't used much :-).

    In wgetstr() you will see the loop:

							Opps
							   |
							   |
							   V
	while ((*str = wgetch(win)) != ERR && *str != '\n');
		str++;
	if (*str == ERR) {
		:

    Yep.  Remove the semicolon and have fun.  Maybe I should post
my list of bug fixes for the 4.2 BSD curses library again
(to net.bugs.4bsd)? If anyone thinks so, then let me know by mail.  If I
get a few requests, I'll post my file of bug fixes again.  It has
been a while.
