Research direction
Start in _reader.c and reproduce the journal.Reader.add_match(_SYSTEMD_UNIT="kres*") case described in the issue, comparing it with journalctl -u 'kres*'. Trace how matches are passed to the systemd journal API and determine the scope needed for glob support. Done means the Python API returns matching units such as kresd@dns1 and kres-cache-gc, with coverage for the behavior if an existing test location is found.

Description
Versions:
- Debian 9 (Stretch)
- python3 3.5.3-1
- python3-system 233-1
- systemd 232-25+deb9u
... but as far as I can tell from _reader.c it applies to master (a402d08da41413507a4ebebf18de897f7ddf1dd2) as well.
For example:
journal_reader.add_match(_SYSTEMD_UNIT="kres*")
always returns empty output. At the same time command journalctl -u 'kres*' lists log for units kresd@dns1, kresd@dns2, kres-cache-gc etc.
It would be nice if the Python API could do the same. For now I'm going to resort calling journalctl as subprocess.
