On same matter actually also 'mcelog --version' outputs everything to stderr. To me it seems to be wrong. Sent patch to Andi upstream, patch was accepted.

Description of problem: In mcelog man page is briefly mentioned --help argument: " When the --cpu=cputype option is specified set the to be decoded CPU to cputype. See mcelog --help for a list of valid CPUs. Note that specifying an incorrect CPU can lead to incorrect decoding output. Default is either the CPU of the machine that reported the machine check (needs a newer kernel version) or the CPU " when you run mcelog --help it would at first write: "mcelog: unrecognized option '--help'" and after that it prints out help message with list of command to stderr and mcelog would return error code 1. Because --help argument is mentioned in manpage I think it should not print "unrecognized option" or it should not be mentioned in manpage. My recomendation. add --help to argument list, print help message to stdout, and return 0 OR remove --help from manpage
