I see.  I guess by the last part you mean that if the next Tramp version (which
will presumably take advantage of this) were to be used with an older Emacs
version, then it would test `(fboundp 'files-equal-p)' and if nil do something
else (e.g. emulate it) to test equality.  Is that what you meant?
