I tried to do it myself, first by checking for Ncurses::KEY_RESIZE in
nonblocking_getch in buffer.rb (couldn't work because of the IO.select),
then slightly less unsuccessfully by catching the WINCH event, but it
looks like the signal isn't emitted in a completely consistent manner
every time I resize the window.

Any advice William? (Of course I'm secretly hoping you're gonna fix it
yourself :)

Sadly no. There have been various attempts, by myself and others to trap
sigwinch (see e.g.
http://www.nabble.com/The-recent-patch-"redraw-screen-upon-sigwinch"-td22662878.html
which is referencing commit 9bc61b52f1a4fb3492e3799240815ed0c2a7b67f)
and to handle Ncurses::KEY_RESIZE, but something always seems screwey.

A free copy of Sup to anyone who figures this out.
