What does "unadorned" mean? I think my suggestion uses a couple of
matching curly braces.

The problem with the current code is clearly seen in the pdf output.
Only the first opening parenthesis is the lower index, the rest -1)
are following that C-with-subindex-opening-parenthesis fully sized.

This is a default behaviour for TeX mathematics. I am not sure how
texinfo is different.
