Good!

Are you going to include the relative '^' link markup?

Noted.

I've given it a go; if it works I'll be able to change my stuff that's
split into a farm so that it's back as one wiki, which will be great!

One problem I found was that it wouldn't work at first because it was
complaining that the function "bcadd" didn't exist.  This is because my
version of PHP was compiled without support for the bcmath library.

So I changed this line:

 $hg = "g" . bcadd($g,1);

to

 $hg = "g" . ($g + 1);
 
And that seemed to work.

Any particular reason why you used bcadd rather than the simple "+"?

Well, you could make a $SearchPatterns pattern for subgroup pages...

$SearchPatterns['subgroup']['group'] = '/^[^-]*-[^-]*-/';

Wouldn't it work to then have a pagelist template which checks the value
of $g2?

(:if !equal "{<$g2}" "{=$g2}":)
{=$g2}
(:ifend:)
 
I haven't tried it, but hopefully it would work.
