<literal>\K</literal> can be used to reset the match start since
PHP 5.2.4. For example, the pattern <literal>foo\Kbar</literal> matches
"foobar", but reports that it has matched "bar". The use of
<literal>\K</literal> does not interfere with the setting of captured
substrings. For example, when the pattern <literal>(foo)\Kbar</literal>
matches "foobar", the first substring is still set to "foo".
