Both of these observations are true.  The log messages are eventually
logged by listeners registered on the global message bus.  For logging
to syslog this is src/libcharon/bus/listeners/sys_logger.c and for
logging to files it's file_logger.c in the same directory.  There are
other loggers in individual plugins.  Of the two loggers above only the
syslogger limits the group string to 4 characters, so increasing the
buffer there should allow you to see the longer group names.

Just out of curiosity, what's the reason you want to change these in the
first place?
