Thanks!

In cc-vars.el, "syntactically valid identifiers" appears earlier in the
paragraph, so when "valid identifiers" appears later, the interpretation
is clear.

In idlwave.el, "valid identifier" is used in a comment.  I think it's
ambiguous (on its own, without studying the surrounding code), but since
it's just a comment, I don't care so much about it.

(This is as of Emacs 25.0.91; I didn't check the latest in the emacs-25
git branch.)

I have a slight preference for removing "valid" from the Info text,
since that change makes the text a little more concise.  But I'd also be
fine with changing to it to "syntactically valid identifier".

cheers,
