Moving the conversation here from https://github.com/python/cpython/pull/12732 for David.

I previously suggested HeaderParseError because of the fact that we could fail to parse a value into a Header Object in the above scenario.

@r.david.murray Would it be more appropriate to have something like a "PolicyError" in case where the policy's max_line_length isn't long enough to fit the shortest encoded word?
