I started emacs with `/mnt/emacs-25/src/emacs -Q`

I confirmed that 256 colors "worked" by doing M-x list-colors-display
RET, and noting that there were about 256 lines of output, with plenty

I typed M-x server-start RET.

In another terminal on the same machine, I typed `TERM=xterm
/mnt/emacs-25/lib-src/emacsclient -c`.  That displayed a *scratch*
buffer, as I'd expected.

In that new frame, I typed `M-x list-colors-display RET`.  I noticed
that now there were only eight lines of output.

I did C-x 5 0 to delete the new frame, then back in the original frame
again typed `M-x list-colors-display RET`, and noted that there were
still only eight lines of output.
