Foreground color broken when background color specified

[dolandemort]

When specifying a background color, any specified foreground color is improperly displayed. To reproduce, use:

/echo -aCblack,Cbgyellow test

The expected result is black font with yellow background, but the actual result is red font with yellow background.

ah, here:

/ /echo -aCbgblue,BCred Foo!

doesn't work.

/ /echo -aBCred,Cbgblue Foo!

works!

Ok, I figured out why.

It's because the BG colour flag overlaps with the FG colour variable itself.

now, this is a bit terrible because I don't know if the high bit is used, it doesn't LOOK like it from a cursory glance, but that made echo work properly again.
