Hm...  That command describes the mode, and whether the current .el file
uses lexical binding or not isn't really tied to the mode, so I think
that sounds a bit confusing.  The user may believe that we're talking
about whether the mode uses lexical binding or not.

That does sound more useful -- I often find jumping back to the start of
the buffer to check.

`emacs-lisp-mode' could display that somewhere in the mode line, I
guess?  But where?  Perhaps among the U:**- thing at the start?  Or in
the mode stuff?

So instead of

(Emacs-Lisp)

we'd get

(Emacs-Lisp Lexical)

when we have lexical binding in the current buffer?  Does anybody have
an opinion here?
