PHPCS 3.x compat: remove php 5.2 work arounds and PHP 5.2 specific code

 	 * Check if a content string contains a specific html open tag.
 	 *
-	 * {@internal For PHP 5.3+ this is straightforward, just check if $content
-	 * contains the tag.
-	 * PHP 5.2 however, creates a separate token for `<s` when used in inline HTML,
-	 * so in that case we need to check that the next token starts with the rest
-	 * of the tag.
-	 * I.e. PHP 5.2 tokenizes the inline HTML `text <span>text</span> text` as:
-	 * - T_INLINE_HTML 'text'
-	 * - T_INLINE_HTML '<s'
-	 * - T_INLINE_HTML 'pan>text</span> text'
-	 *
-	 * We don't need to worry about checking the rest of the content of the next
-	 * token as sniffs using this function will be sniffing for all text string
-	 * tokens, so the next token will be passed to the sniff in the next iteration
-	 * and checked then.
-	 * Similarly, no need to check content before the '<s' as the bug will break up the
-	 * inline html to several string tokens if it plays up.}}

+	 * @since 0.13.0 No longer allows for the PHP 5.2 bug for which the function was

+	 * @since 0.13.0 The $stackPtr parameter is now optional. Either that or the
+	 *               $content parameter has to be passed.
 	 *
 	 * @param string $tag_name The name of the HTML tag without brackets. So if
 	 *                         searching for '<span...', this would be 'span'.
-	 * @param int    $stackPtr The position of the current token in the token stack.
+	 * @param int    $stackPtr Optional. The position of the current token in the
+	 *                         token stack.

+	 *                         passed.
 	 * @param string $content  Optionally, the current content string, might be a
 	 *                         substring of the original string.
 	 *                         Defaults to `false` to distinguish between a passed
 	 *                         empty string and not passing the $content string.
