> Is this _complete() necessary?

It is not.  Though _complete won't actually change the buffer if the
trailing character matches, I've removed it.  The '/' is added prior
to each call here [1].

Using trace2, `real_pathdup` takes around 40 usecs on my machine
compared to 10 usecs for an empty region.

Please see the cover letter for v3 of the patch series for additional
details on both of these items.
