granted, this was wrong.

I'm uncertain this is great. I'm certainly not enamored by the
phrasing. Offhand "you would liked cloned" would be better assuming
the structure is correct. I think 'a specific revision up to which you
would like included in the clone' is perhaps more accurate, although
it's definitely too wordy.

I believe that 'include the graph from null to this revision in the
clone' is probably technically correct, although I don't believe we
speak about 'null' often in help. FWIW, I've recently started adding
more roots to my repositories, so I'm used to having rather disjoint
graphs (and certainly temporarily graphs with more than one classical
root).

hg init; touch 0; hg add; hg commit -m 0; hg up -r null; touch 1; hg
add; hg commit -m 1; touch 2; hg add; hg commit -m 2;
hg clone -r 0 -r 1 . x
