>Description:
fetch seems to use environment variable http_proxy even though it is going to fetch a file via ftp:

[jakobbg at nusse ~]$ set | grep proxy
http_proxy=http://proxy.starshipping.com:8118/

[jakobbg at nusse ~]$ fetch ftp://ftp.vim.org/pub/vim/patches/6.3/6.3.001
fetch: ftp://ftp.vim.org/pub/vim/patches/6.3/6.3.001: Not Found

[jakobbg at nusse ~]$ wget ftp://ftp.vim.org/pub/vim/patches/6.3/6.3.001 
--11:00:54--  ftp://ftp.vim.org/pub/vim/patches/6.3/6.3.001
           => `6.3.001'
