Not much to say here but I realised that the formatting done by
print_freq_handler() add extra whitespaces when not needed e.g. when used for
the current_channel output. I'm thinking about refactoring print_freq_handler()
to get_freq() and return the float which in the end will let the caller do the
formatting.

As an example to this problem default channel of 13 for channel page 0 with the
openlabs SPI board for RPi will print 2 whitespaces instead of one which would
look better.

	current_channel: 13,  2415 MHz

It's not a big deal but I've put it on my todo list.
