Title: Corrected small bug that puts the message in place of the progname

TaggedLogging places the message part in the progname. This does not cause an issue with the standard Logger. However, with Loggers like Syslogger the end message looks like:

My message: [0123] My message

This is a simple fixe that solves the issue.
