[Bioperl-l] I'm 'breaking' write_seq in bsml

[Peter van Heusden]

As per the discussion on making SeqIO 'safe' to use, I'm going through 
the code in Bio/SeqIO/*.pm and ensuring that write_seq() returns 1 if it 
succeeds, and undef if it fails. At the moment the bsml module returns 
the XML object from write_seq, so making this module consistent with all 
the others breaks backwards compatibility.

Is this a problem for anyone?
