All of the above say what were done.  A summarizing sentence before
all of the above would make the proposed commit log message perfect,
perhaps:

    The previous step added the necessary machinery to implement the
    "--force-if-includes" protection, when "--force-with-lease" is
    used without giving exact object the remote still ought to have.
    Surface the feature by adding a command line option and a
    configuration variable to enable it.

    - Add a flag ... to indicate that ...

    - Introduce a configuration option ...

    - Update 'remote-curl' to ...

    ...


Also, in the proposed log message for [1/3], especially near its
end, how "--force-if-includes" interacts with "--force-with-lease"
was described.  The description should be added to the log message
of this change, as it is what introduces the end-user facing
feature.  The description can also be in the log for [1/3] as well,
but not having it here for [2/3] is unfriendly to the readers.

I think OPT_BOOL takes a pointer to int, not unsigned, as it is
OPT_SET_INT in disguise, and you can see that a near-by 'progress'
that also is fed to OPT_BOOL() is 'int' so you can mimic it.

Let's not add this helper function.  Instead just open-code a single
liner at its two callers.  It makes it easier to read and understand
the flow and the logic in cmd_push() and cmd_send_pack().

The comment does not add any value as you are already using a
descriptive constant name.  Drop it to follow suit of existing if
statements nearby.

Thanks.
