Since 664059fb62 (Felipe Contreras, Apr 17 2013, transport-helper: update
remote helper namespace), a 'push' operation on a remote helper updates
the private ref by default. This is often a good thing, but it can also
be desirable to disable this update to force the next 'pull' to re-import
the pushed revisions.
Allow remote-helpers to disable the automatic update by introducing a new
capability.

I feel really stupid for sending so many versions now :-(. v3 was
fixing a whitespace issue, but forgot to re-apply the change I did
manually while sending v2, hence the commit message was wrong
(dont-update-private -> no-private-update).
Not terribly important, but if it's still time, this one should be
correct.

When choosing between 'push' and 'export', Git prefers 'push'.
Other frontends may have some other order of preference.
