m4a/m4p support ?

[mangeot]

Hello,

I like very much your program. I use it to tag mp3 files from various sources.

I was wondering if your program could open m4a/m4p files?
I use kid3 on my mac as a graphic interface to edit the tags and it can open m4a files, but unfortunately, it is not available as a command line tool!

I display the debug output here:

id3edit --readonly --showheader "Bob Marley/Rastaman Vibration/1-03 Johnny Was.m4a"

ID3V2_Open failed with error -2!
