[PATCH 3/7] t4026: test "normal" color

If the user specifiers "normal" for a foreground color, this should be a noop (while this may sound useless, it is the only way to specify an unchanged foreground color followed by a specific background color).

We also check that color "-1" does the same thing. This is not documented, but has worked forever, so let's make sure we keep supporting it.
