Right.  So here is a working patch, porting over my own SOCKS5
code with slight adjustments for lynx.  It took hours to realize
that PARSE_HOST requires a protocol prefix, _what_a_mess_.  Note
the diff was finally produced on v2-8-9rel_1, i tried several tags
from v2-9-0dev_4a downwards, but could not get something
compilable.  (But git cherry-pick'ing the patch worked.)
I hope you like it, it works fine for me here?

Ciao, and a nice Sunday i wish from Germany!
