Feature request: new function start-remote-process

[Michael Albinus <michael.albinus@gmx.de>]

Hi,

with Emacs 22.1, the function process-file has been introduced. It is an
extension for call-process, which let programs execute a remote host
when default-directory is remote. It is implemented via a file handler.

start-remote-process shall behave similar: if default-directory points
to a remote host, the corresponding program shall be executed there.

By this, packages like compile.el or vc.el could extend their
functionality to remote hosts.

Note that Tramp 2.1 offers a simulation of this behaviour already, which
works so far. Because this simulation is based on a defadvice of
start-process, this cannot go into Emacs trunk (and it has also further
undesired side effects which must be avoided).

Best regards, Michael.
