[BioPython] parsing SP records

If you could send the ID of the swissprot record that is giving the
parser problems, that would be a big help towards helping us sort
out the problem. We'll be happy to try and fix the parser to handle
the record -- all file formats, including Swissprot, are moving
targets since what is allowed in the files can change regularly. We
definitely do our best to keep up to date and appreciate it when
people let us know of new files that break the parser.

Thanks for the report. Please do send more information so we can
look at the problem.
