Maybe substitute-in-file-name could put a `substitute-in-file-name'
property on the return value and check for that property on its
argument (and do nothing if it is present).
A later call to substitute-in-file-name should then skip over parts of
its argument string which has that property (and only substitute in
parts which are not previously substituted.
That is still not completely fool-proof if the result of
substitute-in-file-name is manipulated in some way which removes the
property and then later passed to substitute-in-file-name again.
