On platforms that don't support SIGWINCH vi can be configured with FEATURE_VI_USE_SIGNALS disabled and FEATURE_VI_WIN_RESIZE enabled. This allows the user to force an update with ^L when the screen is resized.
However, because the SIGWINCH handler hasn't run the virtual screen buffer won't have been updated and the display becomes corrupted. Fix this by calling new_screen() if necessary.
