[BioRuby] Patch for Bug 18019.

[Tomoaki NISHIYAMA]

Hi Anurag,

> I believe Goto-san's mail also implied something on the same line?


Goto-san's mail implied that your file is just incorrect, because  
there are no
such excess newline in the official GenBank releases, and bioruby  
library
is good to return extra entry containing nil on wrong input.

My opinion is even if it is not exactly the same format as the  
GenBank releases,
bioruby library should ignore the excess newline.
My previous mail was to explain why such file are frequently seen,  
showing
that the NCBI website creates such file, and an easy way to reproducibly
obtain such file with reasonably looking way. (Though tools and email  
parameters were omitted)

I am sure he knows well on why the newline cause that problem, and  
need not to
explain on the cause.
The most important issue is the decision of what is the right behavior.
