Description:
------------
If the record contains an (unquoted) empty field followed by a quoted field, the 
empty field is skipped, so all following column positions are off. This happens 
when the delimiter is "\t" but not when it's ",", so it probably has something to 
do with changes related to trimming whitespace. This problem seems to have been 
introduced between 5.3.6 and 5.3.8.

Test script:
---------------
$s = "0\t\t\"2\"\n";
$a = str_getcsv($s, "\t");
var_export($a);


Expected result:
----------------
array (
  0 => '0',
  1 => '',
  2 => '2',
)

Actual result:
--------------
array (
  0 => '0',
  1 => '2',
)
