Bug description: fputcsv() fgetcsv() inconsistency even number backslashes then enclosure char

Description:
------------
If you write a string to file with fputcsv that contains an even number of
backslashes follwed by the enclosure character, you don't get your
enclosure character back when you read it back in with fgetcsv(). Then
you'll get an extra trailing enclosure character at the end of your
string.

Reproduce code:
---------------
$tmp_file = '/tmp/csv_f_up.tmp';

$data_to_write = array('string contains even number of backslashes \\\\"
followed by enclosure char');

echo "data_to_write:\n";
var_dump($data_to_write);

$h_w = fopen($tmp_file, 'w');
fputcsv($h_w, $data_to_write);
fclose($h_w);

$h_r = fopen($tmp_file, 'r');
$data_read_in = fgetcsv($h_r);
fclose($h_r);

echo "data_read_in:\n";
var_dump($data_read_in);

Expected result:
----------------
data_to_write:
array(1) {
[0]=>
string(73) "string contains even number of backslashes \\" followed by
enclosure char"
}
data_read_in:
array(1) {
[0]=>
string(73) "string contains even number of backslashes \\" followed by
enclosure char"
}

Actual result:
--------------
data_to_write:
array(1) {
[0]=>
string(73) "string contains even number of backslashes \\" followed by
enclosure char"
}
data_read_in:
array(1) {
[0]=>
string(73) "string contains even number of backslashes \\ followed by
enclosure char""
}
