emacs -Q

Put the cursor on any function name in the defun for that function.
E.g., put the cursor on foo here:

(defun foo (arg) "..." 42)

M-x debug-on-entry RET M-n

This is pretty much brain-dead behavior.  The default should be `foo',
not `defun'.  At the very least, `foo' should be one of the "suggestions"
available via `M-n'.

The default *is* `foo' (at least if `foo' is defined as a function).
In your recipe, the default is `defun' which is arguably not very
useful, but note that you can't use `foo' because debug-on-entry can
only be used for functions that are already defined, so `foo' would not
be a better default.

Oops.  Sorry about that.
