It doesn't matter much in my case -- I'm just trying to ensure that
the user of Polipo gets an error message that makes sense.

What about defining a tor-specific extension to SOCKS that provides
both a user-readable error message instead of an error code?  I'd be
quite willing to implement support for that in Polipo, and I have no
doubt that so would the Privoxy people.
