bug#7943: white background is color #e5e5e5 in terminal window

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.

For compatibility with 8-color text terminals that cannot produce the
bright colors, IIRC.

Some text terminals can produce bright white by combining white with
another text attribute (bold, if I'm not mistaken).  Having 8-color
terminals without "white" would be confusing.

We do use "gray" on terminals that don't have this historical
precedent, see w32console.el, for example.
