If we add comment stripping for values to the config parser, how would you add
a value with # characters?

"With some escaping mechanism."

Yes, but how would that mechanism work? Whatever we use will break backwards
compatibility. Personally, I think it was a mistake to not have a general
escaping mechanism in the config file in the first place, but that's
hard to undo now.

Also, I don't think we should add comment stripping in the authz code
(or whatever code that consumes config values), since then, to be
consistent, we should do it everywhere and then we face the same
escaping problem.

I think the solution to this problem is to validate the authz values
more strictly, only allowing legal flag characters. People can insert
their nice comments above the values.
