test buildhtml options, because ``--local`` is broken.

Build-HTML Options
------------------
--recurse               Recursively scan subdirectories for files to process.
                        This is the default.
--local                 Do not scan subdirectories for files to process.
--prune=<directory>     Do not process files in <directory>.  This option may
                        be used more than once to specify multiple
                        directories.
--ignore=<patterns>     Recursively ignore files or directories matching any
                        of the given wildcard (shell globbing) patterns
                        (separated by colons).  Default: ".svn:CVS"
--silent                Work silently (no progress messages).  Independent of
                        "--quiet".
