if a single text file name is supplied as argument (e.g.: 'webpmux my_long_list_of_frames.txt'), the command line arguments are actually parsed from this file. Tokenizer will remove space, tabs, LF, CR, returns, etc. + changed ImgIoUtilReadFile() to return a null-terminated data, for convenience. + misc clean-up in the code BUG=webp:355 Change-Id: I76796305641d660933de5881763d723006712fa9 ---
