Actually I see the cc-mode code uses it with a group.  And js.el too
(perhaps copying cc-mode).  Does it have some subtle effect of skipping
the /*, or is it outright wrong?

I suppose the intention is to pick up non-breaking spaces or whatever
other flavours of whitespace.  Unlikely to arise in practice in
programming language stuff.  Is there an obvious ill effect?
