v4.4.1

Fixed

• SyslogEntry and SecureLogEntry accept fractional seconds, so
  journalctl -o short-precise (Sep 23 16:55:34.125733) is read as
  syslog instead of falling back to RawEntry (#45). The clock column still
  has to be a whole HH:MM:SS, optionally followed by . and 1-9 digits;
  10:00 and x10:00:01 are still rejected (#2).
• RSyslogEntry found the clock by splitting on -, which only works west
  of UTC: any +hh:mm offset or Z raised ValueError, and so did a
  fraction of anything but six digits, and one such line sank the whole log
  to RawEntry (#11). It now matches the whole RFC 3339 timestamp, and its
  vote requires the whole first column to be one.
• Fixtures test19 (short-precise journal, same content as test16: its hash
  and graph output are identical) and test20 (RFC 3339 with +02:00,
  +05:30, Z, -0400 and 1-9 digit fractions).
