window resize causes completion problems when menu completion in progress with linewise at least

[bkerin]

$ echo "$BLE_VERSION"
bash: 0.4.0-devel4+e300c68: command not found
$ echo "$BASH_VERSION ($MACHTYPE)"
5.2.15(1)-release (x86_64-pc-linux-gnu)

It's not a large issue by any means but it seems that when a window is resized while a manu completion is in progress the display becomes corrupt. Ideally the SIGWINCH would trigger a redraw correct for the new window, or less ideally the next input would do so. Note that I have no idea if this is remotely practical or worthwhile to implement though.

Ah, yes. I recognize this problem. It can also be messed up when the number of lines changes due to the temporary insertions of completions.
