hmmm, okay, so I added that location as well. ;-)

here is a patch that will make `dvbscan` to list the series of
initial-data-files being installed in the system. It works on
all of /etc/dvb/dvb-?/* /usr/share/dvb/dvb-?/* and of course
that /usr/share/doc/packages/dvb/dvb-?/* ... it may help user
to get a clue (it's shown when no cmdline arguments are given).

Btw, I was thinking over to give this function its own getopt
but hey "-l" is taken :-/ ... and what makes me wonder, why
is there "q:" while the usagedoc says it does not require an
argument (i.e. --quiet)?

cheers,
