I am not too happy in detecting features by checking version numbers of
programs. This will work for a while, and this will generate problems
later on, likely.
Maybe it is sufficient to add a hint to the Tramp manual, that the
following setting in the ssh config file is useful, when applicable by
the underlying ssh version:
Host *
ControlMaster auto
ControlPath /tmp/%...@%h:%p
