You are. ;-)
Actually, the rule for EOL reads:


EOL ::= [#xD#xA]+

which allows for *several* newline characters (and a mix of Unix-, Windows-
or Mac-style newlines, for that matter).
So you can have as many empty lines as you wish between two triples, that's
still correct.

However, you made me realize that a valid n-triple file may *not* end with
a newline.
So if you want to concatenate them, you should insert a newline between two
files, to be on the safe side.
