Automatically instrument forms for Edebug when setting
breakpoints inside not-yet-instrumented forms.
* lisp/emacs-lisp/edebug.el (edebug-form-data-symbol): Add
optional `instrument-if-needed' argument.
(edebug-find-stop-point): Likewise.
(edebug-modify-breakpoint, edebug-set-conditional-breakpoint):
Pass t as `instrument-if-needed'.
