>Description:
The new apropos in 6, doesn't seem to give reasonable results.  While trying
to find the usbdevs(8) command, I ran:
apropos -C usb

and got:
alcyone# apropos -C usb
usb (4) Universal Serial Bus driver
usbhid (3) USB HID access routines
cdce (4)   USB Communication Device Class Ethernet driver
ulpt (4)   USB printer support
uep (4) USB eGalax Touchpanel
ukbd (4)   USB keyboard support
cue (4) CATC USB-EL1201A USB Ethernet driver
uts (4) USB generic touchscreens
umodem (4) USB modem support
ucom (4)   USB tty support

If I want to find usbdevs, apparently I have to do -C8 ?? 

Aside from that, I find the new format of man -k to be obnoxious.  Can we
revert to the historical display, or maybe make it sensitive to an environment
var, like OLDMAN=YES ? :)
        
>How-To-Repeat:
man -k usb

There are lots of other examples, I haven't been able to find lots of commands
