Revert "compile, parse_acl: treat foo/CREATER (no regex metas) correctly"

This reverts commit 33fc0a7e9f.

Was causing too much trouble with access reporting (basic and expanded)
because of the extra ^ at the start...

The paranoia referred to in that commit was this sequence:

  - admin creates a named (non wildcard) repo using config file push
  - somehow that gets deleted (OS error, corruption, ...)
  - admin just asks anyone with a current repo to push it to auto-revive
    it (because we allow people with "W" access to non-wildcard repos to
    auto-viv repos)
  - if you're treating this the same as a wildcard creation, you end up
    making this guy the "creater" of that repo, which means he can add
    users etc...

We resolve that paranois by disallowing autoviv of "W" access repos at
all...  Only "C" access repos can be autovived by a user (this will be
in the next commit)
