Does "valid identifier" mean syntatically correct, or does it mean that
the identifier is in the tags table.  Please clarify the documentation.

We probably should just remove the word "valid" from there.

That depends on how you will change the behavior ;-)

I've changed it like we discussed.

However, after reading the quoted text, I'm not quite sure we need to remove "valid". To my eyes, "valid identifier" in that text means "syntactically valid", rather than "an identifier defined somewhere in the current project". The latter would be "an existing identifier", I guess?

But that's my impression. If that word raises questions, maybe it doe need clarification, or a replacement. The only option that came to my mind, however, is more unwieldy: "discernible identifier", and it doesn't mean the same thing.

The two other uses of "valid identifier" we have inside Emacs (in cc-vars.el and idlwave.el) also mean "syntactically valid".

Mike, thoughts?
