I don't know what created it.  Wouldn't surprise me to find out it was
created in Microsoft Word....  It was given to me as a example input
file/test case.

Yeah, there is that.  On the other hand, then we should make the
equivalent change and have the Bio::SeqIO object fail on them even if
it's told that they're Fasta (e.g. by -format or by guessing based on
filename).

I was just frustrated when stuff worked up until the moment that I
uploaded the file into a tool via the web (at which point it ended up
in an oddly named file and the guessing heuristic broke).

I'd vote for relaxing the constraint, but, hey....
