>From Bron Gondwanda <brong at fastmail.fm>:

I did an audit of the uses of "open" where a file might still exist from a
previous crash and be hardlinked somewhere we care about.  There was one more
location.

This patch just adds an unlink before the stage file gets created during
append_newstage.  It's trivial and boring, but makes me feel safer about the
integrity of my possibly-hardlinked spool files!
