revert an improper location change to anonymous authors

Reverting pull request #2326.  For some reason, closing a
pull request does not prevent it from being used.
Pull request #2327 was based on top of pull request #2326,
so even though pull request #2326 was closed, accepting
pull request #2327 causes pull request #2326 to be
accepted, even when the files used by pull request #2327
are completely independent from pull request #2326!  *sigh*
