patch 9.0.1747: screenpos() may cause unnecessary redraw
Problem: screenpos() may cause unnecessary redraw.
Solution: Don't unnecessarily reset VALID_WROW flag.
VALID_WROW flag is only used by two functions: validate_cursor() and
cursor_valid(), and cursor_valid() is only used once in ex_sleep().
When adjust_plines_for_skipcol() was first added in patch 9.0.0640, it
was called in two functions: comp_botline() and curs_rows().
- comp_botline() is called in two places:
- onepage(), which resets VALID_WROW flag immediately afterwards.
- validate_botline_win(), where resetting a VALID_ flag is strange.
- curs_rows() is called in two places:
- curs_columns(), which sets VALID_WROW flag afterwards.
- validate_cline_row(), which is only used by GUI mouse focus.
Therefore resetting VALID_WROW there doesn't seem to do anything useful.
Also, a w_skipcol check (which resets VALID_WROW flag) was added to
check_cursor_moved() in patch 9.0.0734, which seems to make more sense
than resetting that flag in the middle of a computation.
While at it make adjust_plines_for_skipcol() and textpos2screenpos() a
bit less confusing:
- Make adjust_plines_for_skipcol() return "off" instead of "n - off".
- Use 0-based "row" in textpos2screenpos() until W_WINROW is added.
