luasocket.http and repeating headers

[Cosmin Apreutesei <cosmin.apreutesei@...>]

Just noticed that luasocket.http concatenates repeating headers with a
comma which makes them impossible to parse if the header value itself
contains a comma. Maybe a better idea is to put them in a table when
they are repeating, like:

http.lua, line 55:

        -- save pair in table
        if not headers[name] then
            headers[name] = value
        elseif type(headers[name])=='string' then
            headers[name] = {headers[name],value}
        else
            headers[name][#headers[name]+1] = value
        end
