The "pack-objects" command (and to some degree "repack", too) is
about packing throughout, and --depth/--window is not necessarily
the central piece of the puzzle, and that, together with disruption
of the flow of the original explanation, was the reason why I found
the initial location a bit odd.

You're right---if there is an existing CONFIGURATION section, that
may be a much better place.  There are configuration variables that
affect how the packing works other than the core.bigFileThreshold,
and attributes like "delta" would also affect the outcome.

Describing all in one CONFIGURATION section would be valuable.

What I queued is with the following ready to be squashed in,
primarily because I was lazy and didn't have time/inclination to
look for a better place myself ;-)

Thanks.
