Michael, it's become evident that people are using Tramp without
realizing that they are using Tramp.  I think this is great, and
you should be quite proud.  The "transparent" works! ... mostly
If  it's not quite perfect let's improve on it.  This is one of those points.

In this and in the other and yet in the other decade , I've
always appreciated when I don't need to restart my restart my
Emacs (ugh) because I worry about when variable values I'm
experimenting with are read.  This is a Lisp machine after all :-)

At the very least, the documentation of tramp-remote-path should
state that the variable doesn't take immediate effect and that
something must be done (is it really restarting Emacs, or is there
some M-x tramp-cleanup-* thing that has to be done?)

So, if "anything goes", is such a minimal docstring patch
acceptable?

João
