Hrm, does the updated text explain the usefulness of the option clearly
enough?

It may be just me, but I find the untouched "The default is to assume"
line somewhat out of place after this update.  When reading, without any
of the options, we read all three places and consolidate them (stopping
after the first file that has the definition is a funny exception that
"--get" does; in general the internals read all of them so "--get-all"
output is a better way to understand what you wrote in your configuration
files), and when writing, without any of the options, we write to the
current configuration file.

The paragraph should first be restructured to describe read and write
cases separately, and then '--local' should be described, perhaps like
this?

	When reading, the values are read from the system, global and
	repository local configuration files by default, and options
	'--system', '--global', '--local' and '--file <filename>' can be
	used to tell the command to read from only that location.

	When writing, the new value is written to the repository local
	configuration file by default, and options '--system', '--global',
	'--file <filename>' can be used to tell the command to write to
	that location (you can say '--local' but that is the default).
