Description:
------------
When making a query on a MSSQL DB using mssql functions an extra space is added to the end of output.  This is causing trouble with scripts of mine that check to see if the querried field is empty to determine whether or not to display some text.

The bug mentioned at
http://bugs.php.net/bug.php?id=25777
describes the problem but was marked as bogus.  I think when the fix for http://bugs.php.net/bug.php?id=25777 was made it in advertently left an extra space in results.

Reproduce code:
---------------
//once connected to the db
$sql="Select name from contacts";
$result=mssql_query($sql);
$row = mssql_fetch_array($result);
//assume there is one entry in the table 
//with an empty string as the value for 
//name
if (!empty($row["name"])){
  echo "Name: " . $row["name"];
}else{
  echo "Name value is empty";
}

Expected result:
----------------
Name value is empty

Actual result:
--------------
Name:
