>Description:
When you type apropos <text> (or man -k <text>) on the console (which is
set by default to vt100 in /etc/ttys), extra characters (formatting?) appear
around the colored parts.  For example: "$<2>options$<2> ($<2>4$<2>)" instead
of "options (4)" 
>How-To-Repeat:
Login from the console, which is set to vt100 in /etc/ttys instead of one
of the other local consoles (such as ttyE1 or ttyE2) which are set to wsvt25.
Setting the TERM environment variable to wsvt25 while on the console solves
the display problem for that session. 
>Fix:
I'm not sure if the proper fix is to set console to wsvt25 in /etc/ttys or
something else.
