I had a similar reaction on reading Philip's patch. I think your
suggestion is better. We could even shorten it to just:

  Use 'git help git' for an overview of the system.

Looking at "git help git" I actually think the DESCRIPTION section could
do a better job of being a first entry-point for new readers of the
documentation. But I don't think that needs to be a blocker for what
we're discussing here.

Yeah, I almost suggested something like:

  Use 'git help git' for options and environment variables that affect
  all subcommands.

I'm not sure if that points people in a useful direction, or if it is
getting too much into the weeds (again, probably the description section
of git(1) could talk about how to find which documentation where.

I also think it should point to git-scm.com for the hyper-linked
documentation, since it's less ugly than the stuff at git.github.io, but
that's really getting off-topic. :)
