      When I use the SyslogAppender and specify a suffixPattern that starts with a whitespace or other character that is not [ logback seems to just append the string (until the first occurence of certain characters, e.g -) to the internal "%nopex" string. Subsequently it fails to parse the %nopexXXX string and prints something like:

      Jan 12 15:54:14 think %PARSER_ERROR[nopexXXX] [main] LogTest DEBUG FROM JAVA...

      to syslog. Had a look in the sourcecode, but couldn't figure out where it goes wrong, but I could confirm that if I add a whitespace to the string in this line

      String prefixPattern = "%syslogStart

      {" + facilityStr + "}

      %nopex ";

      there is no PARSER_ERROR. An additional whitespace in the logmessage though (I can live with that though). I need to be able to specify a string that doesn't start with [ though for some crazy reason (almost funny – every other character would have been ok as far as I could figure out...).

      Any chance that could be looked into and included in one of the next releases?

      Thanks in advance...
