I've used diff.<TYPE>.xfuncname with great success for file <TYPE>s that
I defined myself. However, now I would like to append an extra pattern
to the TYPE=cpp case (for which git has builtin patterns). Is there an
easy way to do this?

I figured I could open-code the builtin patterns from "userdiff.c", and
then append my new pattern to those, but it looks kinda gross :)

Unfortunately, no, the config system has no notion of "append to this
value". 

And I think adding such capability would not be easy.  Well, perhaps
we could support '+=' in addition to '='?

        So you are stuck with extracting the builtin value (which
annoyingly, you cannot even get without looking at the source code!),
and repeating it in your config file.

I wonder if `git var -l` could provide all default values :-P
