+### Fixes
+- Fix `logger` default severity, use **.notice**, like other logger
+  implementations.  Was .info, which is of lesser severity, affecting
+  some use-cases negatively (loss of logs)
+- Drop extra leading space in log message in libsyslog RFC3164 format,
+  two spaces between `proc[pid]:`, or plain `:`, and the message
+- Drop trailing space in `logger` messages read from command line
