Vanilla "git rebase" defaults to --fork-point that in some cases
makes behavior very different from "git rebase <upstream>",
where --no-fork-point is assumed. This fact was not mentioned in
the DESCRIPTION section of the manual page, even though the case of
omitted <upstream> was otherwise discussed. That in turn made actual
behavior of vanilla "git rebase" hardly discoverable.
While we are at it, clarify the --fork-point description itself as well.
