This feels like a funny place to look up the config. How would you
override it if were to have a "--no-stash" command line option?

Good suggestion.

This is a common mistake we saw in submissions by many new
contributors, and a good practice to avoid it is to start from a
command line option without a configuration variable.  I.e. make
sure that

    $ git status --show-stash
    $ git status --show-stash --no-show-stash

work well.  After that, add support for status.showStash and make
these also work well:

    $ git -c status.showStash=false status --show-stash
    $ git -c status.showStash=true status --no-show-stash

These two new ones need to result in command line options overriding
the configured default.

And have these four getting tested in test scripts.
