There is a bug in the exclude code (found by jrollins in the
--with-excluded series) but also present in master.  None of the
current tests were finding it so the first patch adds two tests.

The bug (and test failure) do not appear in all configuations: on my
main test machine (an oldish debian testing 32bit userspace with a
64bit kernel and xapian 1.2.7) all tests pass. On my laptop (a recent
debian testing 64bit userspace and xapian 1.2.8) one of the new tests
fails.

The second patch fixes the behaviour for me but I don't see why it
should make a difference: searches for A and not B should give the
same results as A and not (A and B). It could be a bug in xapian, it
could be that I am not allowed to reuse queries as I do (is query1 =
query1 and query2 allowed?) or it could be some memory use bug on my
part.

Anyway the "fix" is small which should help narrow down the actual
cause.

Best wishes
