[O] Bug: org-map-entries seems broken

[T.F. Torrey]

Hello,

I have a function that uses org-map-entries to build a list of entries.
It worked until recently.  Now, it fails with simple combinations.  For
instance, 'LEVEL=1' matches what it should, and 'weblog' matches what it
should, but 'LEVEL=1+weblog' does not match the intersecting set, or
anything at all.  Did I miss a change in the syntax, or maybe did a
recent refactoring introduce an error?  Does anyone else use this kind
of matching and have it work?

Thanks in advance,
