Summary:                    raptor fails to parse trig files with dos line
endings
Description: 
a trig document which includes dos end-of-line indicators fails to parse.

imports$ rapper -v
2.0.13
imports$ cat bad.trig
<http://example.org#graph>
 { <http://example.org#this> a <http://example.org#that> . }

imports$ cat ok.trig 
<http://example.org#graph> { <http://example.org#this> a
<http://example.org#that> . }

imports$ rapper -c -i trig bad.trig 
rapper: Parsing URI file:///root/imports/bad.trig with parser trig
rapper: Error - URI file:///root/imports/bad.trig:2 - syntax error
rapper: Failed to parse file bad.trig trig content
rapper: Parsing returned 0 triples
imports$ rapper -c -i trig ok.trig 
rapper: Parsing URI file:///root/imports/ok.trig with parser trig
rapper: Parsing returned 1 triple
root at graphity:~/imports# 


the difference is the presence of the use of cr/lf to indicate the end-of-line:

imports$ od -a bad.trig
0000000   <   h   t   t   p   :   /   /   e   x   a   m   p   l   e   .

0000040   h   t   t   p   :   /   /   e   x   a   m   p   l   e   .   o
0000060   r   g   #   t   h   i   s   >  sp   a  sp   <   h   t   t   p
0000100   :   /   /   e   x   a   m   p   l   e   .   o   r   g   #   t
