That is also Julian's proposal. I dislike it, because there might be
many packages Tramp has never heard about. And even for the packages
contained in core Emacs, it will be an endless story: think about all the
vc-BACKEND calls of list whatever.

The charme is also, that packages can precisely say, which file has been
changed. Tramp could only guess `t' or `nil'. Parsing `args' of
`process-file' might also not a good idea, I believe. You cannot not
know for sure, what is a filename, and what is something else.
