Re: Emacs 256 color support.

[Josh Howard]

It was suggested I take this conversation here. Basically, I'm trying
to get 256 color support to work in Emacs 21.3.50.2, with little luck
so far.  I don't really know if this is an issue with any other
version of Emacs, which is why I hesitated in bringing it up as a bug.
At any rate, with TERM set to xterm-color and otherwise being able to 
view 256 colors in an xterm, Emacs doesn't seem to be able to display
them all.

8 is what's returned. I suppose it's 8, but I'm also able to do all
of the bold colors, which is why I mentioned 16.

Just for fun, I did take a screenshot of my xterm showing the colors:

Just for information's sake, this is on a FreeBSD box running XFree86
4.3.0, with:

GNU Emacs 21.3.50.2 (i386-unknown-freebsd4.7, GTK+ Version 2.2.3) of
2003-09-26

And xterm "179" off of Dickey's site.
