I had written some lengthy arguments, but when I wanted to back up
with data and facts, the first search result[1] convinced me this is
a bad patch as when a user asks for help specifically, they want it
to easily be piped, i.e.

    git --help |grep pull

instead of

    git --help 2>&1 |grep pull

So I'll drop this patch.
Thanks,
Stefan
