And for "destructiveness" see the implementation in lib/query.cc _notmuch_exclude_tags:
It replaces every matching tag in query_string and exclude_tags with an empty string ""
in the exclude terms. This most likely results in <match_all_documents> which can be
seen as a bug, if you want; removing would be better but also more expensive.
For a quick test run your test program with different queries/exclude_tags with
NOTMUCH_DEBUG_QUERY (man notmuch) set to a non-empty value and look what happens ;)
