My reading of the manual for 

	git config --global user.name Foo2 Bar

is this:

       Multiple lines can be added to an option by using the --add option.

Does not apply here - no `--add` option, so no new value should be added.

       If you want to update or unset an option which can occur on multiple
       lines, a POSIX regexp value_regex needs to be given. 

does not apply: First: no "--unset" variant is used here leaving only "update".
Second: before that command there is only one value.

       Only the existing values that match the regexp are updated or unset.

Since "Two" does not match the previous value and `update` is the only 
described case left I'd expect that the command changes nothing.I don't
understand how the description allows `git config` to add a new value,
because the manual talks about "update" twice, nothing about adding.
