On many systems, the en_US locale uses a collating sequence that treats
accented characters as unaccented, just like fr_FR or other iso-8859-1
based locales.  Use "LC_COLLATE=C" if there's any chance you have accented
characters in your documents.  This is done in the 3.1.6 snapshot.

As it turns out, the first htmerge pass, after htdig, is needed on each
database before you run htmerge -m.  The code that handles the merging
of two databases expects that the wordlist has already been purged of
control records that htdig uses to tell htmerge about documents to update
or delete.
