We ought to remove inactive tests!

In running the syntax tests over the latest update of the SPARQL test
suite, I encountered the following positive test, which fails for me:


The query is the following:

PREFIX og: <http://ogp.me/ns#>
	?page og:audio\:title ?title

As far as I can tell, this test case is out of date: colons in prefixed
localnames are no longer to be escaped, and grammar production
PN_LOCAL_ESC (see http://www.w3.org/TR/sparql11-query/#rPN_LOCAL_ESC)
does no longer contain the ':' character as a legal value for escaping.

There is a negative syntax test which covers exactly the same issue:



PREFIX : <http://example/>
   :a :b :c\:z .

Clearly, these two tests are contradicting each other, and I suspect
that the first one should be removed.
