I am not a pro on GNU texinfo. I just replaced

@expr{C_(-1)} with @expr{C_{(-1)}}

, despite syntax checker's complaints,
and run make pdf. And the resulting pdf looks the way it should look,
with all of (-1) in the sub-index.

I am not sure if that is the way it should be solved, or it is just a
co-incidence that it works for the pdf output.
