bug#7055: Tramp bug: file-remote-p is now broken, breaks Emacs generally

[Drew Adams]

Actually, this Tramp bug prevents me from being able to use Emacs at all - the
error pops up all of the time.

emacs -Q
 
In *scratch*, call file-remote-p with a remote file name (can be a fictitious
file):
 
(file-remote-p "/foo-2.foo.com:/usr/share/emacs/21.3/lisp/README")
 
You get this error:
 
 "Symbol's function definition is void: tramp-compat-call-process)"
 
Note: For some reason "SimonTatham" seems to be hard-coded here. Never heard of
him.
