revise curses_raw_print()

For curses, behave like tty by keeping a count of messages issued via
raw_print, then if that is non-zero issue a prompt and require the
player to acknowledge them before it erases the screen.  Mainly so
that complaints during RC file processing will be seen.

For tty, force getret() to be an unconditional routine instead of
sometimes a routine, sometimes a macro which calls another routine.
