With the current patches, you can use --function-context together with
--context=<num> to specify a minimum number of context lines to show,
even beyond function boundaries.

I'd expect a --context=function option to be equivalent to -W -C0 and
--context=<num> to be equivalent to -C<num> --no-function-context, so
the syntax would be limited in that regard (or be unintuitive to me).

We can still add it on top, though.
