A revision always implies all its ancestors by definition --
a fundamental concept of every DVCS.

Not sure we need to repeat that in the text of this specific
option.

Also the help text already has:

    If you use the -r/--rev option to clone up to a specific revision, no
    subsequent revisions (including subsequent tags) will be present in the
    cloned repository. This option implies --pull, even on local repositories.

But I'm fine with changing it to

-r  clone only this revision, tag or branch

But maybe this could be changed in a separate patch?

After all, my patch does not change -r ...

Can you provide an updated help text? Or a patch for it?
