Actually, the correct place to do this is in bbsh when it's interactive.

Our existing terminal checking code should be taught about $LINES and 
$COLUMNS, and should check them as a fallback for when the ioctl returns 0.  
That's a small enough amount of bloat to be acceptable in exchange for the 
functionality, it's basically atoi(getenv("LINES"))...

I added it (svn 16167).  Dunno if it works, have to set up a test environment 
that hasn't got a controlling terminal but has $LINES and $COLUMNS set...

Anyway, I can teach bbsh that when it's launched interactive, do the probing 
thing if standard querying doesn't work to determine terminal size.  That'll 
set $LINES and $COLUMNS for its child programs, and svn 16167 should 
theoretically be able to take it from there...
