Sorry, I am merely reporting this as a usability bug and I don't intend
to get too deep into it (too little time :(). If I can work around it I
do that and get back to my work. For this bug I actually tried to get
used to it. I failed so I spoke up but not to blame any change.

You seem to be fairly confident on the approach chosen. Good and I look
forward to its improvements. Please be considerate on two things:

1. Leave room for other usage habits;

2. Rely less on heuristics. As also suggested by Stefan, do what he did
   with elisp--local-variables, i.e. code walk the expansion of the sexp
   and pick out the var/function postions/names. elisp--local-variables
   performs really well because it `guess' it right.

HTH,
Leo
