cat? grep? even awk? :-) On production systems, only cat [*] makes sense
probably (to inspect the output when you write matching rules). It's
simple enough to support, and also helps to keep userland ingnorant about
implementation details.

Yes, no practical problem I guess.

Ok, I'll do the same -- should amount to emitting new event from
config_found.

[*] Note that cat is likely to work fine for FreeBSD as well ("by
    conincidence"), cat's read buffer is likely to be >= 1024, which
    is the size of a message -- so it will be lucky enough to read
    one whole message per read() call.
