Ah, yes. I think when I first made my changes there I had recursion in
mind, much the way authz_line_applies_to_user recurses to handle inversion,
but it evidently never actually came to fruition.

I'm not really sure how to do that, but if I remember and have some spare
time, I'm sure I can figure it out :-) If you were hoping to have them
before doing the check-in, then it'd probably be better if you did them. If
it's okay for them to arrive over the week-end, then I'll put it on my TODO

I did notice one thing in the patch, a comment I neglected to update when
switching from having '$' to having '$authenticated':

+ /* If we get here, then the rule is:
+ * - Not an inversion rule.
+ * - Not a pure-anonymous rule.
+ * - Not a wildcard rule.

"Not a pure-anonymous rule." should read something like "Not a special
authz token."

Other than that, your changes look good to me. We'll have to wait to hear
back from your build to be certain :-)

For what it's worth, while I didn't have a Subversion unit test for these
changes, their initial development was done in a separate mini-project
which tested them before I went and integrated them into authz.c.
