After a conversation with Daniel, I now intend to make some changes
myself, based loosely on 59371e4c138fa9fde27352d4d35e3f321d41d4e4
(in gnupg/upstream-for-work).

Changes I intend to make are:

 * In the configuration and initialisation code, replace the Tor
   specific configuration knowledge with a resolv.conf option to use
   any SOCKS server, called something like `socks_server' or
   `adns_socks_server'.  The value would be an IPv4/IPV6 literal, plus
   port number; or, alternatively, a pathname (for use with AF_UNIX,

   My understanding is that whatever in Tor is using adns generates
   its own private resolv.conf anyway; and there is no need for
   general adns clients to be able to specify, as such, use of Tor.

   (If /all/ adns clients on a host should use the Tor server via
   SOCKS, then putting the socks configuration in the host-wide
   resolv.conf would be appropriate.)

   Does that make sense ?

 * Drop the whitespace patch.  Instead, include a patch to
   .gitattributes to suppress git's moaning.

I don't have an easy way to test this code.  If I send you a reference
to a git branch, would you be able to test it for me ?

a private address which bypasses my fierce spamfilter.
