Subject: Special files should appear to have a link-count > 0
X-Git-Url: http://git.neil.brown.name/?a=commitdiff_plain;h=ff6a4f4dec44836b9c07613d1a652f84aa42667f;p=LaFS.git

Special files should appear to have a link-count > 0

otherwise they might get deleted when we put them for
the last time, which would be bad.
