Bug description:preg_replace doing double replacement
Description:
------------
The preg_replace is doing a double replacement when the parenthesized
pattern is the whole string.
Test script:
---------------
define ('EOL', "\n");
$patterns = '|(.*)|';
$replacements = '$1-new';
$line = 'OLD';
$line = @preg_replace($patterns, $replacements, $line, -1, $changes);
print $line . EOL;
Expected result:
----------------
'OLD-new'
Actual result:
--------------
'OLD-new-new'
