Tramp uses already a hack. Obviously, it cannot use process-environment
as-it-is on a remote machine, because it is, ahem, a remote machine and
not the local one. Therefore, Tramp forces only environemt variables,
which are not set in the defauzlt value of process-environment, to the
remote. The idea is, that specific remote environment variables are
added to process-environment via a let-binding.

A buffer-local process-environment is another, new game player.
