[vorbis-dev] ogg123 -k 1:59 patch.ogg # minutes and seconds

[Hans Schou]

Hi

I have helped a user with a little patch for ogg123. He uses ogg123 
for very big files, often more than an hour (blind books). When he 
breaks the book and later on want to go back to the same chapter, it 
is a little troublesome to calculate the seconds. Minutes is much more 
convenient as it is what is written on the screen.

I guess my patch is a little buggy and would like to improve it upon 
request (guidelines are welcome). Anyway, here it is:

PS: Is there a library function for this kind of stuff?
