Fixing namespaceTTL (was recursively calling itself)

Thanks for the fix, applied to trunk

I notice the method definition looks a bit odd in general - @afs should namespaceTTL() have a similar definition to localnameTTL() where it first calls localname() and then applies escaping?

i.e. should namespaceTTL() be calling namespace() and then applying escaping to the results?

[escowles]

I think that the escaping is only needed for the localname -- the namespace URI will usually contain characters (.-/#) that would be improperly escaped by escape_PN_LOCAL_ESC().

[afs]

@escowles is right - escaping is only allowed in the local part. Also, the return from namespaceTTL is a IRI, to go in <...>, not the prefix name that is written in output as a bare word.
