All I can say is the current behavior is quite annoying when more than 8
colors are available. Many colors have very low contrast against the grey90
background, and there's no way I can see to set the background to
brightwhite. This forces me to set my TERM so that all I get is black and
white, which can also be hard on the eyes.

I guess I can try and hack my xterm.el, but it definitely seems like a bug
to me.
