Viewing message with only an HTML part currently fails on my Mac, spitting out the output of "w3m -o" to my face. This happens because the version of w3m that I pulled from Homebrew was not built with support for Gopher, hence errors out when passed the gopher_proxy option... which the "html" script does unconditionally. This patches fixes the script to not pass "*_proxy" options that are not built into the w3m binary. Signed-off-by: Simon Martin <simon@nasilyan.com> Acked-by: Robin Jarry <robin@jarry.cc>
