[parted-devel] mac+msdos partition table mixup

I've got a bug report ( https://launchpad.net/bugs/909424 ) where it 
appears that the disk originally had a mac partition table on it, and 
was reformatted with an msdos partition table.  Parted still recognizes 
the mac partition table though.  It looks like this is because whatever 
wrote the msdos partition table attempted to preserve the code area of 
the existing sector, which to the mac partition table, is the signature, 
so it still looks like a valid mac sector 0.

Should parted be changed to deal with this and if so, how?  I suppose it 
could probe the msdos partition table before mac, and if that is 
recognized, then it would take precedence over mac.
