Lynx already does its own recognition of escape sequences without needing
keypad() - probably has been doing so longer than keypad() was there.

I find (with ncurses) that I _can_ get an ESC through - i.e. can do
KEYMAP:^]:something - if I press ESC twice.  That's because LYgetch
waits for the next key after it sees the first ESC.
