Re: Emacs 21.2 -- debugger-frame-offset is 8, should be 6

[Richard Stallman]

    The guidelines on bug reporting basically don't trust users to analyze
    problems,

I wouldn't put it that way.  When a user does, as you did, show us
precisely what is wrong and what the fix is, we appreciate that
greatly.  (Thank you!)

Our advice about giving a test case is because (1) if the user doesn't
provide a fix, we need the test case to start from, and (2) if the
user does provide the fix, the test case enables us to verify that it
is right.

      As a side effect they add a new function and keystroke
    to debug.el, so that Emacs can help find the correct value of
    debugger-frame-offset in the future.

Very interesting -- thanks.
