[ESS-bugs] new font-locking in *.Rnw: [[...]] looks wrong

[Martin Maechler]

I should have noticed earlier,
but  "of course" did not,...

But then, it may not be so important, as we will (?) move to a
new shiny  bug-free (:-)  Rnw mode rather sooner than later.

Anyway,
I attach  foo.Rnw   which is an excerpt of a student's exercise,
where in  "  Samp[[p.sd(s), nL]]  "
the part inside [[....]]  is  bold-face fontified similar to 
'if' or 'for' ... definitely the wrong font.

Can you confirm?
