[linux-dvb] Tzap and exit after tuning

[Kimmo Koivisto <kimmo.koivisto@surfeu.fi>]

Hello

When tzapping to channel, tzap does not exit when tuning is done. Szap seems 
to have option "-x" to exit when tuning is done.

I'd like to have the same feature in tzap. I copied the -x code from szap to 
tzap (see attached patch) , is this the correct way to do it and if yes, 
could this be applied to CVS?

Regards
Kimmo Koivisto
