Maybe nobody implements that because `edebug-backtrace' is planned to be
rewritten so that it gets better than "Better than nothing..." (see
docstring)?

However, until that happens, maybe this problem should be solved.


Can't we just append some code like this:

  (goto-char (point-min))
  (while (progn
  	 (goto-char (+ (point) 2))
           (skip-syntax-forward "^w_")
           (not (eobp)))
    (let* ((beg (point))
           (end (progn (skip-syntax-forward "w_") (point)))
           (sym (intern-soft (buffer-substring-no-properties
                              beg end)))
           (file (and sym (symbol-file sym 'defun))))
      (when file
        (goto-char beg)
        ;; help-xref-button needs to operate on something matched
        ;; by a regexp, so set that up for it.
        (re-search-forward "\\(\\sw\\|\\s_\\)+")
        (help-xref-button 0 'help-function-def sym file)))
    (forward-line 1))

to `edebug-backtrace' (the code is from `debugger-make-xrefs')?


Thanks,

Michael.
