The attached patch enhances the behaviour of CTRL-W_CTRL-_ in visual mode.
If CTRL-W_CTRL-_ is pressed in visual mode, Vim will try to change the
height of the current window to match the visual selection and scroll
the text so that all of the selection is visible.
I didn't know whether to document it in visual.txt or window.txt...
Left it in window.txt along with documentation for the original
CTRL-W_CTRL-_.
