I confirm that it's indeed a limitation of gencmdlist.sh.  It may be
possible to handle it by using C preprocessor before sed, but I don't
think it's an urgent issue.  It's shouldn't be a problem for properly
indented source.

I don't understand how this is related.

I actually don't feel good about using anything other that a C compiler
or preprocessor to parse C sources.

It's working for now, but if we want to make it more reliable, I'd
rather not ask a "sed guru".
