So, you want to end up with

    [url "http://example.com/"]
	insteadOf = http://example.org
	insteadOf = http://example.net

but you cannot get there with only "git config VARIABLE VALUE", because that syntax is used to clear the existing values for VARIRABLE before setting it to VALUE.

Have you tried

    $ git config url.http://example.com/.insteadof http://example.org

that clears existing values for url.http://example.com/.insteadof and sets it to "http://example.org", then immediately follow it with

    $ git config --add url.http://example.com/.insteadof http://example.net

that keeps existing values for url.http://example.com/.insteadof and adds another value to the same variable?
