Description:
------------
In CGI mode $_POST is not filled with all passed variables. As Apache module works as expected.

Test script:
---------------
<?php
$fp = fopen('php://input', 'r');
echo stream_get_contents($fp).PHP_EOL;
var_dump($_POST);



Expected result:
----------------
% curl --data "lname=a&lpwd=%251&signin=" testscript.php
lname=a&lpwd=%251&signin=
array(3) {
  ["lname"]=>
  string(1) "a"
  ["lpwd"]=>
  string(2) "%1"
  ["signin"]=>
  string(0) ""
}
% curl --data "lname=&lpwd=%251&signin=" testscript.php
lname=&lpwd=%251&signin=
array(1) {
  ["lname"]=>
  string(0) ""
  ["lpwd"]=>
  string(2) "%1"
  ["signin"]=>
  string(0) ""
}


Actual result:
--------------
% curl --data "lname=a&lpwd=%251&signin=" testscript.php
lname=a&lpwd=%251&signin=
array(3) {
  ["lname"]=>
  string(1) "a"
  ["lpwd"]=>
  string(2) "%1"
  ["signin"]=>
  string(0) ""
}
% curl --data "lname=&lpwd=%251&signin=" testscript.php
lname=&lpwd=%251&signin=
array(1) {
  ["lpwd"]=>
  string(2) "%1"
}
