Tramp manages it locally already. The point is when it comes to
environment variables a user wants to be set on the remote host. He
could write of course

(let ((process-envrionment ...))
   (setenv XXX ...)
   (process-file ...))

But $XXX would be set for the local case as well, because Tramp must
start with a local call-process or start-process. This could result in
undesired behaviour.

For the most obvious case, Tramp offers the variable tramp-remote-path.
People could apply something like this before calling process-file:

     (add-to-list 'tramp-remote-path "/usr/local/perl/bin")

But a more general mechanism, applicable for any environment variable on
the remote host, would be desirable, IMHO.
