+ 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.
