System: NetBSD shadow 7.0 NetBSD 7.0 (GENERIC.201509250726Z) amd64

Machine: amd64
>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.

 If you do not use serial console, replacing vt100 with wsvt25 in /etc/ttys
 is fine.

 However, apropos should not emit colour sequences when the terminal does
 not support them (and I seem to recall this has been fixed already, maybe
 there is just a pullup to -7 missing).

 vt100 terminfo description does have smul/rmul (underlining) sequences
 defined, but they include delays "$<2>", which is what you see.

      A delay in milliseconds may appear anywhere in a string
      capability, prefixed with a dollar sign and enclosed by angled
      brackets, such as $<5>.

 So the problem is that apropos doesn't use terminfo correctly.

 PR/50344: Stephen Fisher: apropos shows formatting on console with vt100 term
 type. Can't print terminfo sequences directly; need to process them with
 ti_puts() to handle padding. This removes the padding delays, and stricly
 could break on slow terminal hardware, but they way the code is structured
 makes it impossible to fix properly (since the formatting strings are
 passed in the query).
