There was also an unrelated typo in the newly-added documentation. So
here's a replacement 10/10 with the fixed documentation.

Subject: [PATCH] clone: accept config options on the command line
Clone does all of init, "remote add", fetch, and checkout
without giving the user a chance to intervene and set any
configuration. This patch allows you to set config options
in the newly created repository after the clone, but before
we do any other operations.
In many cases, this is a minor convenience over something
like:
git clone git://...
git config core.whatever true
But in some cases, it can bring extra efficiency by changing
how the fetch or checkout work. For example, setting
line-ending config before the checkout avoids having to
re-checkout all of the contents with the correct line
endings.
It also provides a mechanism for passing information to remote
helpers during a clone; the helpers may read the git config
to influence how they operate.
