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". 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.

Thank you for confirming!
