Martin, this is because of this change in the call to
change_frame_size by init_display:
@@ -6171,7 +6069,8 @@ init_display (void)
t->display_info.tty->top_frame = selected_frame;
change_frame_size (XFRAME (selected_frame),
FrameCols (t->display_info.tty),
- FrameRows (t->display_info.tty), 0, 0, 1, 0);
+ FrameRows (t->display_info.tty)
+ - FRAME_MENU_BAR_LINES (f), 0, 0, 1, 0);
change_frame_size_1 then calls adjust_frame_size with the value one
less than the terminal height, and adjust_frame_size plugs that value
into FrameRows:
if ((FRAME_TERMCAP_P (f) && !pretend) || FRAME_MSDOS_P (f))
FrameRows (FRAME_TTY (f)) = new_lines;
This lies to Emacs about the terminal height, and cmcheckmagic catches
that.
I don't understand why you subtract FRAME_MENU_BAR_LINES, that sounds
wrong at least for TTY frames. (We could add that back inside
adjust_frame_size, but it's IMO a bad idea to spread this non-trivial
logic between 2 functions.)
