Description:
------------
There's some mistakes with the French translation of sprintf().

Problem in example 3 :
 - There is 2 unwanted \ (line 2)

Problem in example 4 :
 - Same as told for example 3.
 - Line 3, a quote mark isn't escape and an other is missing at the end.

See attached code for more details.

Reproduce code:
---------------
Actual code for example 3 :

<?php
$format = 'Le %2\$s a %1\$d singes';
printf($format, $num, $location);
?>


Actual code for example 4 :

<?php
$format = 'Le %2\$s a %1\$d singes.
           C'est un beau %2$s, avec %1$d singes.;
printf($format, $num, $location);
?>


Expected result:
----------------
Expected example 3 :

<?php
$format = 'Le %2$s a %1$d singes';
printf($format, $num, $location);
?>


Expected example 4 :

<?php
$format = 'Le %2$s a %1$d singes.
           C\'est un beau %2$s, avec %1$d singes.';
printf($format, $num, $location);
?>
