The docstring of 'beginning-of-defun-function' says that the
function shall return non-nil when it found the beginning
of a defun. This is specially important because the calling
code decides when to move point depending on the return value.
* lisp/progmodes/js.el (js-beginning-of-defun)
(js--beginning-of-defun-flat): Return non-nil when the beginning
of a defun is found. (Bug#64283)
* test/lisp/progmodes/js-tests.el (js-mode-end-of-defun): Add a unit
test.
