revset: remove part of the commonancestors() comment
The reason is that:
- it shows up in "hg help revset", but it doesn't look like
documentation targeted at users
- it doesn't make sense to me: it doesn't say what happens with < 2
revisions, and is not quite right because my understanding is that
this revset was created precisely because "::x and ::y" was not
quite the same (when x and y don't evaluate to singletons).
