No, it has much less.  But we tried all the colors in tty-colors.el,
and the 88-color xterm distinguishes them enough for us to decide that
88 colors are like 256 for all practical purposes.

In other words, 88-color xterm will support any faces that could be
defined in the future as well as the X version of Emacs.

Yes.

Yes.
