should error when --dry-run option applied to non-local command

If I invoke a *vanilla* command **leaf** (subcommand), off of a *local* command **base** (which supports `--dry-run`), then `argcmdr` should raise an error alerting me to the option's incompatibility, rather than executing the command.

No file or test is named in the issue. Start by reproducing a vanilla leaf command invoked through a local base with --dry-run, then trace argcmdr's command parsing and dispatch; done means the incompatible option raises an error instead of executing the leaf command.
