a2b529ead2 --help option and help command should print to stdout not stderr
--help and help are successful commands so output should not go to error.

    QE teams have requested this change, also users doing docker help | less
    or docker run --help | less would expect this to work.

    Usage statement should only be printed when the user asks for it.
    Errors should print error message and then suggest the docker COMMAND --help
    command to see usage information.

    The current behaviour causes the user to have to search for the error message
    and sometimes scrolls right off the screen.  For example a error on a
    "docker run" command is very difficult to diagnose.

    Finally erros should always exit with a non 0 exit code, if the user
    makes a CLI error.

Forbid `docker run -t` with a redirected stdin (such as `echo test |
docker run -ti busybox cat`). Forbid `docker exec -t` with a redirected
stdin. Forbid `docker attach` with a redirect stdin toward a tty enabled
container.

e01baa6be7 Auto-update documentation from the output of the cli.
I've re-jigged the run man page so that each option's text begins with the
cli's help text for that flag, and then ay subsequent lines in the man page
are carried forward.
