I think that the old code was more obvious.

pa_namereg_register() could return NULL, you checked for that 
immediately, and acted upon the error. Now you pass this NULL through 
pa_xstrdup(). This causes the reader to think what pa_xstrdup does with 
a NULL. Yes, it returns a NULL, but I had to look at the source.
