That's exactly the reason of my proposal. The proof of concept in Tramp
2.1 did show this deficiency. With the new function, every package could
decide whether to apply start-process or start-remote-process.

A package like gnus shall always use start-process; it is unlikely to
use mail programs on a remote host. In contrary, compile shall use
start-remote-process - when default-directory is local, there is no
difference to the current behaviour.

Best regards, Michael.

PS: The problem with ediff has been worked around in Tramp's CVS version
already, because it disturbs me as well. But it is still a kludge.
