Good to know; it's covered then.

I know.  I'm actually trying to make sure that the escape sequences are
covered, because if the user has to use the --rebindkeypad option,
keycodes mode will be switched off and only escape sequences will be
available.  The same goes for if the terminfo access is screwed up
somehow; for example, Slackware's rxvt-2.7.10 sets TERM to xterm, but
doesn't generate the same sequences as xterm in many cases, so ncurses
won't return the proper keycodes for it.  It's a case of "what should
be" versus "what is", and I certainly wish the two lined up more often.

Good to know.
