The test in the previous patches id:"1331551914-28323-1-git-send-email-markwalters1009@gmail.com" triggered the bug accidentally. It accidentally set the exclude tags to be "=" and "deleted" rather than just "deleted". The non-existent "=" tag (i.e., the tag that does not occur anywhere in the Xapian database) triggered the bug. First we correct the tests to just set the "deleted" tag, then we add some tests including one with a deliberately non-existent tag. Finally, we modify the exclusion code to avoid the bug. The modification also appears to fix a similar problem for jrollins that I have not yet been able to reproduce. Since the code is now more clearly correct, cleaner and we do definitely avoid a Xapian bug I think these patches can be committed even without knowing why it fixed jrollins' bug. Finally these apply to current master (not to the --with-excluded series).
