Log: Fixed Bug #55674 (fgetcsv & str_getcsv skip empty fields in some tab-separated records)
which was introduced by r311543

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',
)
