Happy to help:) I stumbled upon the bug because I use sr -p in a little
script that allows using surfraw searches from within elinks. I attach
it herein in case someone might find it useful. The script should be
saved as (part of) ~/.elinks/hooks.lua

Cheers,

-- You need to have surfraw installed, obviously, and your lua install should have io.popen.

function match (prefix, url)
    return string.sub (url, 1, string.len (prefix)) == prefix
end

function tosurfraw (str)
    return "surfraw -p " .. str .. " 2>/dev/null"
end

function goto_url_hook (url, current_url)
    if match ("!", url) then
        sr = tosurfraw (string.sub (url, 2))
        urlfile = io.popen (sr)
        finalurl = urlfile:read('*all')
        urlfile:close()
        return finalurl

    else
        return url
    end
