The 'text' and 'binary' options to md5sum do nothing, and are confusing. Perhaps we can't remove them, in case people have scripts which use them -- but we should at least make sure that 'md5sum --help' and the man page make it clear that they do nothing on real computers.
It is not always true that they do nothing. They do nothing on GNU system - where text and binary file style is the same. More detailed informations about those options are in 'info md5sum' (in some cases is necessary to use both - man and info pages - coreutils have usually more informations on info pages). Anyway - those options are not depricated even in the latest upstream release and are used for compatibility with systems where binary and text differ(like MS-DOS). I don't think that it is useful to create patch which will only remove all the text about -t / -b option from man,info and help page and to keep it forever in Fedora package - because I doubt that will get accepted by upstream. It could be IMHO even more confusing for users(if options -t/-b are accepted, but not shown in man/info/help). So closing NOTABUG, but feel free to add your comments (maybe it could be more helpful to add something to man/help page what will say that text and binary options will have same output on GNU system).
