R14B gen_tcp:recv/2,3

dear list,

i read from R14B release's readme:
http://erlang.org/download/otp_src_R14B.readme

OTP-8831  For a socket in the HTTP packet mode, the return value from
gen_tcp:recv/2,3 if there is an error in the header will be
{ok,{http_error,String}} instead of {error,{http_error,String}} to be
consistent with ssl:recv/2,3.

i'm not really sure i did understand well: does this mean that all
code which relies on gen_tcp:recv/2,3 needs to be rewritten? for
instance, will this code generate a no matching clause in R14B in case
an error is produced?

case gen_tcp:recv(Sock, Len, RecvTimeout) of
    {ok, Bin} -> {ok, Bin};
    {error, Reason} -> {error, Reason}
end.

i, for one, surely hope i've misinterpreted this statement..

r.
