Ah, good.  So, although the current text is technically correct if
interpreted that way, it is ambiguous.  Why do we need to have a 0
return value also possibly mean no frames have been decoded?   If
frame_size_ptr is set to 0, that always means no frames have been
decoded, without regard to the return value.  And a return value of 0
should mean zero bytes were used, without regard to what frame_size_ptr
is set to.  They seem mutually exclusive to me...
