+         If terminal size can't be retrieved and $LINES/$COLUMNS are not set,
+         this option makes vi perform a last-ditch effort to find it:
+         vi positions cursor to 999,999 and asks terminal to report real
+         cursor position using "ESC [ 6 n" escape sequence, then reads stdin.

+         This is not clean but helps a lot on serial lines and such.
