I tried this out some time ago, but found it unsatisfactory.  The
problem was that I sometimes spuriously triggered completion when I only
intended to indent, because the current line happened to be correctly
indented.  It is often difficult to tell by eye whether a line is
already indented.

(Another related topic is that of binding TAB to lisp-complete-symbol in
read-expression-map; this was brought up on emacs-devel some time ago,
but the discussion petered out IIRC.)
