Fair enough.

That works for me, at least in js-mode.

While not a general solution to all weird files one might encounter
while working in Emacs, it at least makes js-files behave as expected.
And in a fairly reusable manner too: I can copy this code and I'm home
free.

Would pushing this up to cc-mode's c-populate-syntax-table function also
be considered an option? Or does that just sound on overall way too
risky?
