1. Instrument any defun/macro for edebug with C-u M-x RET eval-defun
2. Remove instrumentation with M-x edebug-remove-instrumentation RET
3. Check the chosed symbols plist: M-x (symbol-plist 'whatever-you-used)

Edebug data will be present in plist after instrumentation is removed.

Attached patch is suggestion to fix 'edebug-remove-instrumentation' to
remove unnecessary data after instrumentation.

Is edebug-remove-instrumentation only function that can remove edebug
instrumentation?

I am not though sure, if some other place needs to be patched, I am
thinking mostly of edebug-read-and-maybe-wrap-form.
