well... rxvt-unicode-256color was the effect of the checkins for termcap.src
for conf/152713 and conf/153164

The earlier one suggests that the naming came from rxvt-unicode's sources.
Checking that, it seems that the rxvt-unicode entry specifies 88 colors,
while the rxvt-unicode-256color entry (close to rxvt-256color) does 256.

However, the rxvt-unicode entry in FreeBSD was added for conf/117323,
which equated it to rxvt-mono (no color), with some changes for function-ke=
ys.

On the other hand, the rxvt entry uses color, which was overlooked in
conf/117323:

# Termcap entry for rxvt-unicode, taken from http://cvs.schmorp.de/rxvt-uni=
code/doc/rxvt.7.html#I_need_a_termcap_file_entry
rxvt-unicode|rxvt-unicode terminal (X Window System):\
	:SF=3D\E[%dS:SR=3D\E[%dT:bw:ec=3D\E[%dX:kb=3D\177:kd=3D\EOB:ke=3D\E[?1l\E>=

	:pa#64:Co#8:AF=3D\E[3%dm:AB=3D\E[4%dm:op=3D\E[39;49m:tc=3Drxvt-mono:

Following the clue from the comment, the example using no color was present
in rxvt.7 until it was removed in version 9.05 of rxvt-unicode.  The current
documentation contains no examples (the termcap/terminfo are only separate
files).
