Some man pages are colorized, some aren't

[Curt Daugaard <box8s@sbcglobal.net>]

Hi,

I'm running Sid.  The majority of the man pages I bring up display raw 
escape characters.  Some exceptions that do display correctly are  
calendar, finger, and hd.  The pager is most.

This happens in the console and in xterms.

Can anyone point me to a possible cause?

Thanks very much.

Curt
