Now `repo download . 1402` would download the change numbered 1402
into the current project and check it out for the user, using a
detached HEAD. `repo sync .` would back out of the change and
return to the upstream version.
Multiple projects can be fetched at once by listing them out on
the command line as different arguments.
Individual patch sets can be selected by adding a '/n' to indicate
the n-th patch set should be downloaded instead of the default of
patch set 1.

This way users are well aware of which account we used when the
uploads are complete, so they can be certain to sign into the web
application with that user identity.

If the reflog for the upstream branch has only 1 entry in it, as
the branch has been updated only once, we can get back the 0{40}
object id from `git rev-parse upstream@{1}`, in which case we should
consider it to be the same as if upstream@{1} is not defined.
