Hi,

The behavior in question only affects SOCKS version 4 [1] and is shown
in the second attachment. The first revises some helpers and adds
additional tests I was too lazy or thoughtless to include in recent
patches.

The third contains a naive attempt at a fix but may suffer from my
inadequate grasp of Emacs coding systems [2]. Please advise if that's so
and/or I need to hit the books (or get my head examined).

Thanks,
J.P.


[1] The function socks--open-network-stream assumes all v5 addresses to
be of type 3, which means a domain name of variable length, presumably
of the LDH character set: https://tools.ietf.org/html/rfc1928#section-5

[2] Re coding-systems and proposed fix: I'm wondering if I should have
used encode-coding-string (or something else) instead. Also: while
socks--open-network-stream is perhaps the real culprit because it
creates the offending string, I figured it's more resilient to have the
function doing the sending to massage any IP address it encounters.
