Browse source 
(__rn): Drop str and use hex_str instead.
	(__small_vsprintf): If 'l' modifier has been found, print subsequent
	multibyte or wide char string using the s, S, or W options in extended
	hex value layout.

	* fhandler_disk_file.cc (fhandler_disk_file::readdir): Print WCHAR
	and resulting multibyte filename in extended hex value layout in
	debug output.
