Subject: Silly mistake - restore-cursor-pos doesn't make sure the cursor
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=refs%2Fheads%2Fzlib-dll;p=PuTTY.git

Silly mistake - restore-cursor-pos doesn't make sure the cursor
position is inside the screen (it might not be if the screen has
shrunk since the save of cursor position). Thanks to Robert de Bath.
