I'm not able to come with acceptable English anyway.

Hmm - ok, then maybe this is really not necessary to explain.  I don't
know.

I mean the aspect that Stefan had fixed here: that a local variable
created inside a let-binding of the "same" variable survives the
termination of the `let' expression.  Which means in particular: `let'
seems to not restore the value of the variable because the former
binding is "shadowed" by the buffer local binding.  This is similar to
what is described in the "Warning" paragraph in the manual I cited, but
happening without changing the current buffer.

Could we maybe melt this case into this "Warning" paragraph?

Michael.
