:Is it safe to change instances of "SvPV(Foo, n_a)" to "SvPV_nolen(Foo)"?

I had assumed so, but looking at the code I'm not so sure - I don't
understand why SvPV_nolen is any more than:
  #define SvPV_nolen(sv) SvPV(sv, n_a)

:PS  What's the difference between SvPV and SvPVx?

I don't know - the code for SvPVx appears to be a slightly slower way of
doing the same thing. I don't know why it exists, particularly given
the potential for confusion with SvPVX.
