[ESS-bugs] noweb-mode fails to find chunks containing [[...]] in title

[Rafael Laboissiere]

Dear ESS developers,

I am using ESS 5.3.8~svn3917-1 in my Debian system and noticed that
noweb-mode fails to find chunks that contain "[[...]]" in their titles. This
is a quite frequent construct in noweb files, used to typeset parts of the
title in typewriter font.  Thew problem happens because the "[" character
confuses the regexp searches.

A patch that fixes the problem is attached below.  I hope you will consider
it in the next release of ESS.

Cheers,
