diff mercurial/commands.py @ 14323:a79fea6b3e77

debugindex etc.: add --changelog and --manifest options

These open the changelog and manifest, respectively, directly so you don't
need to specify the path.

The options have been added to debugindex, debugdata and debugrevlog.

The patch also fixes some minor usage-related bugs.
