Browse source 
This implements
https://gist.github.com/rockorager/e695fb2924d36b2bcf1fff4a3704bd83,
in-band window resize notifications.

When user enables private mode 2048 (in-band resize
notifications), *always* send current size, even if the mode is
already active.

This ensures applications can rely on getting a reply from the
terminal.
