This is just one of many cases that exhibited the issue.  It is one of
the least excusable, because it has no need to touch the filesystem at
all, but there are plenty of others, such as "tar cf - ." (which, while
it does use the filesystem, also has no justification for caring what
its working directory is).

Of course, if current tar(1) doesn't suffer from this, the symptom as
described is gone - but if pax-when-run-as-tar still exhibits it, then
it is still a bug, just a bug in pax rather than a bug in tar.

I think it would make more sense to reclassify it as a PR against pax
rather than a PR against tar.  (Especially if pax exhibits a similar
insistence on getcwd() working even when run as pax.  I don't know
whether it does; I don't run anything recent enough to usefully test it
on, and I don't even know pax-as-pax enough to test it anyway.)
