Hello Dmitry and Felipe,

I’ve taken a stab at formatting Felipe’s fix for arrow function indentation according to the coding standards.  Compared to his patch, I made some trivial name/doc changes, and changed

(progn (forward-char) (js--looking-at-broken-arrow-function-p))

to

(save-excursion (forward-char) (js--looking-at-broken-arrow-function-p))

since we probably want to undo the forward-char in case the form returns nil.

In order to get all the JS indentation tests to pass with make, I also had to make a variable safe file-locally.

Both changes are attached.  They could be applied to the emacs-26 branch.  (Or master, but emacs-26 would be preferable so we can deliver it sooner.  I tested on both branches.)
