Sorry about the trouble. Somehow I didn't test using -nw with a
HAVE_WINDOW_SYSTEM build. It should be fixed now.

Previously it did, but each implementation of that procedure was a no-op
for tty frames. The issue is that FRAME_RIF procedures shouldn't be
called for tty frames; I didn't realize that FRAME_RIF was NULL for tty
frames instead of a blank struct. I wonder if that should be changed to
avoid this in the future?
