They can be extremely long, but our code doesn’t tend to have these
very long names.

I’m not sure what we could do to shorten them unless we really don’t
care very much about accuracy. For example we could drop the class
names, but we don’t limit classes to one per file, so we can easily
end up with two classes with the same method name in the same file.
Alternatively we could not list the parameter labels, but we
definitely have methods that only differ by their parameter lists in

FWIW, I’ve not run into any problems so far.

I was working through them when I thought of a neater way to do this,
but it’s probably less like the rest of the code in cc mode. Hopefully
it’s OK. Patch attached.
