I like this. I would suggest using '*:' as your magic prefix, though.
That way, the '*' is less likely to be mistaken for part of the match
pattern itself.

  # Match 'private' directories withing the tags of all repositories.
  [*:/tags/*/private]

Also, in this mode, the match pattern needn't start with '/', right?

  # Match any item named "public" regardless of tree depth.
  [repos:*:*/public]

This leaves open the possibility of a future additional match mode for
regular expressions (using the '^:' magic prefix) should we seek to "go
there".

  # Match the trunk and branches subdirs and their children.
  [repos:^:^/(trunk|branches)(/.*|$)$]

Ugh. I'd *really* prefer not to have to reimplement basic .INI parsing
for various extra-Subversion tools that read and write authz files, such
as ViewVC.
