Bug description:PCRE_DOTALL modifier overrides non-greedy operator
Description:
------------
If the PCRE_DOTALL 's' modifier is specified in the regex, instances of the
non-greedy (lazy) operator '?' are ignored.
Test script:
---------------
$input = <<<END
<p>paragraph 1</p>
<p>paragraph 2</p>
END;
print "Output 1:\n";
print preg_replace('|<p.*?>paragraph 2</p>|', '', $input);
print "\nOutput 2:\n";
print preg_replace('|<p.*?>paragraph 2</p>|s', '', $input);
Expected result:
----------------
Output 1 and Output 2 should be the same, i.e. with the second paragraph
removed.
Actual result:
--------------
Output 2, with the PCRE_DOTALL modifier set, is blank: the first pattern
matched greedily.
