I've noticed that there's a bug in byte-compile-force-lexical-warnings
which causes extra spurious warnings of this kind, so when using
byte-compile-force-lexical-warnings, double check those warnings (which
have been changed in the mean time to use a different formulation) since
they may just be spurious.

E.g. your renaming of a `string' argument to `str' is probably the
result of such a spurious warning.  So I didn't apply this hunk.

When unused function arguments can be removed (as is the case here),
it's generally a better choice than to mark them as unused.

I just installed your patch, thank you, and sorry for the delay,
