bug#15609: 24.3.50; `debug-on-entry' default when cursor is on a function name

[Drew Adams]

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'.
