>Description:
Linux syslogd branch has supported a '-' prefix for files and pipes which causes the syslogd to omit fsync() after each logged line from 1995.  This causes relatively heavy operation if you syslog a LOT of data.

I've ported Martin Schulze's code to BSD syslog.  The code is almost identical.  Linux syslogd is under a BSD license, so this should not be a problem.
