Improve searching for XXX in tidy script (#3303)

Few places where previous version of tidy script cannot find XXX:
* inside one-line comment preceding by a few spaces;
* inside multiline comments (now it finds it if multiline comment starts
on the same line with XXX).

Change occurences of XXX found by new tidy script.
