Fix 'move-to-window-line' when EOB is on last screen line
* src/window.c (displayed_window_lines): Fix an off-by-one error
when the bottom of the last display line is exactly at window's
last pixel. Remove kludgey fix for TTY frames that is no longer
needed. (Bug#15760)
(Fmove_to_window_line): Doc fix.
* doc/lispref/positions.texi (Screen Lines): Clarify and make more
accurate the documentation of 'move-to-window-line'.
