for prefork, where the change to apr-util to have it use the allocator
from the pool passed in is already sufficient.

- check more exactly whether the previous token is correct
- flip the tree from left-weighted to right-weighted, which is
  more natural and more efficient, since we don't need to loop
  up to the root, but just until the next and/or token.
- that way, flip the short circuit evaluation again to cut
  the right side now if possible...

result of the enclosed expression. Since this expression will never
touched again during the tree-building stage, we can safely strip
TOKEN_GROUP from the tree and later evaluate the child directly.

The only side effect of this change is, that grouped strings on the
left side of EQ/NE/etc are now allowed (was invalid before), which
is acceptable IMHO (e.g. (foo bar baz) = zzzip)

is way more useful if we short circuit the left side. So evaluate
the right side first. This, however, reverses my statement about
regex optimization (you have to put them onto the right side of an
&& or || operator to get a chance that the left side will be cutted).

possible if there's no regex on the short circuited side (since it fills
in the backref data). The user may optimize this by putting the regex
onto the left side of the operator.
