Currently it splits the time between programs proportionly with any rounding 
going to the end of a program.  David suggested maybe it all should all go to 
the end of the program but I disagree.  I use 5 / 10 and don't believe I've 
ever used the partial padding except in test cases.

This looks correct.  Sharing transponder/sources would certainly help in many 
cases but because only Australia is effected it is low priority.  I was going 
to work on this after getting this patch accepted.

I currently use a patch that disables soft padding on all channels except 7, 9 
and 10.  It saves a great deal of disk space.
