Terminal type term-256color is not defined

[Jeffrey Walton]

I'm working on a Fedora 1 system.

   $ ssh 172.16.4.138
   Last login: Sun Aug  9 23:39:18 2020 from 172.16.2.10
   unknown terminal "xterm-256color"
   unknown terminal "xterm-256color"

and

    $ emacs test.txt
    emacs: Terminal type term-256color is not defined.

There's one mention of xterm-256color in /etc

   # grep -IR xterm-256color /etc
   /etc/termcap:#    * add xterm-88color and xterm-256color -TD

However, xterm-256color shows up frequently in /usr/local. I think the
xterm-256color may be coming from libtextstyle.
