I actually did this for a while flame groups which I know nobody will 
read - if it's in the crossposts, the article dies.

I actually implemented a patch for this and sent it to Cornelius - it
was done the wrong way around (it wraps the calls to add the group,
rather than just shoving it into the group thing).  Also, I've been
doing Fortran and ML rather than C in the past year or two and it shows.
If anyone wants it I can try to dig it out.

I don't actually use the patch since I maintain the Debian package and
like to use the package I actually distribute.

Probably not, but I didn't really understand why you were worried so I
thought I'd explain it anyway.
