I think those who tried "-c remote.*.url" would be helped better by having a see-also in the documentation on "remote.*.url" that refers them to "insteadOf" noting that "remote.*.url" is a multi-value variable and appending different definition will not make "the last one wins". After all "-c" is merely *one* way to append. The next person who gets confused may say "I added remote.origin.url at the end of my $repo/.git/config expecting that the value to be used"; the answer would be the same "the variable is multi-valued; adding a new value is not the right way to futz with it. You either need to replace, or if you do not want to replace, use insteadOf". That is the second reason why the mention of insteadOf does not belong to the description of "-c var=value". Perhaps something like this as a starting point?
