Subject: Ignore special keys returned by the curses getch() function.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=a6d654780e890044fa9039fcb66911f9e2e558d9;p=openbsd

Ignore special keys returned by the curses getch() function.
Prevents canfield from suspending itself when you resize the window.
Canfield is not prepared to deal with anything other than normal
characters so just ignore them.  OK tb@ pjanzen@
