[PATCH] mergetools: add vimdiff3 mode

[PATCH] mergetools: add vimdiff3 mode

[Felipe Contreras]

It's similar to the default, except that the other windows are hidden.
This ensures that removed/added colors are still visible on the main
merge window, but the other windows not visible.

Specially useful with merge.conflictstyle=diff3.

Thanks for an explicit Ack.

I personally think a new backend vimdiff3 can go in 2.0 (though we
are -rc0), as we can read from the patch below, it is very unlikely
to break anything else (I am not sure what these 'hid' are in the
implementation, but even if we had any breakage there, it would not
affect anybody other than vimdiff3 backend).
