Dot locking is the only kind of locking guaranteed to be `supported' on
all/most servers, so I don't see how any other default is sensible.

Maybe I'm misunderstanding something.

Anyway, I think the best might be for nmh to refuse to manipulate (create,
edit, etc.) files that it cannot dotlock. I'm not sure whether that
refusal should be a fatal error for the entire command being executed,
or a warning and partial success of the command.
