rHG98399dd1b96c: errors: make formatparse() an instance method on ParseError

Summary

It's just a little simpler this way.

Don't ask me what the "hg: " prefix signifies to the user, I just left
it as it was. I think we should consider changing the prefixes later
(maybe always use "abort: ", or maybe use more specific prefixes in
general).
