That's exactly the reason why. It doesn't matter if they are called
/tmp/unlink////, because some stupid caller didn't include the final
rm (/tmp/unlink////rm). Just use getprogname() for this, the only exception
would be a program messing with argv[0] first and expecting getprogname()
to work later, but for that you can always call setprogname() too.
