Jurabib 0.52p out of sync with jox 0.1f

Hi Jens and others,

You might actually have got the impression that I faded away from the 
Jurabib scene, but that is actuallly by no means the case. The only 
 issue is that I work with it to complete my dissertation. I 
nevertheless regularly follow its development and install updates, 
although I sometimes miss one.
Up till recently, I had 0.52m with jox 0.1f, which worked excellently. 
Now I installed 0.52p and this turned out to become out of sync with jox 
0.1f. A minor problem which isprobably easy to fix:

Each article title normally appears as: John Jones, `This is the title', 
_Journaltitle_ etc.
It now appears as: John Jones, `This is the title,' , _Journaltitle_ etc.

The comma *before* the final parenthese should be removed (typical 
Oxford style) and the space *after* it should be removed.

I've provided a set of test files. Peculiar is that the standalone 
incollection entry doesn't have the problem, but you will know why. 
Unpublished entries have the problem, so booklet, misc, url, etc will 
have it probably as well. The \citetitle command doesn't have the 
problem, so short forms are probably unaffected.

As far as I can see -- I ran some of the test suite files on it, no 
further problems appeared.

All the best,

Maarten
