The above is overly verbose about how the commit materialized,
compared to the description of the merit of this update.

    push: fix --recurse-submodules breakage

    When b33a15b0 (push: add recurseSubmodules config option,
    2015-11-17) added push.recurseSubmodules configuration option,
    it also changed the command line parsing to allow
    --no-recurse-submodules to override configured default.
    However, the parsing of configuration variables and command line
    options did not follow the usual "last one wins" convention.
    Fix this.

    Also fix the declaration of the new file-scope global variable
    to put it on a separate line on its own.

or something?

Also describe what "slightly improve" really means.  What did the
old one not test that should have been tested?

Thanks.

These days, you can do:

		git -C gar/bage --quiet origin/master master^

instead.
