Good idea,
I've changed your implementation to rely on two new customization
variables `org-babel-noweb-wrap-start' and `org-babel-noweb-wrap-end' as
this provides more flexibility to the backend implementation to place
constraints on the properties of the noweb names.
In you're situation you will now want to set...
(setq org-babel-noweb-wrap-start «
org-babel-noweb-wrap-end »)
Thanks for the great idea,

Hi,
Here's a patch I'm using to change the default regular expression used
to match noweb references.
The default regular expression \\(.+?\\) conflicts with Ruby
syntax and confuses syntax highlighting.
I now set this to «\\(.+?\\)», i.e. using guillemots instead
(AltGr-z and AltGr-x on my keyboard).
Regards,
Sean
