Git config multiple values

Hi,

I'm currently using git version 2.14.2. There is possible to put multiple values into same variable with git config.

Case 1: # git config --global user.name Foo - returns 0 # git config --global user.name Bar - returns 0 and replace Foo to Bar # git config --global user.name Foo - returns 0 and replace Bar to Foo

Case 2:
# git config --global user.name Foo - returns 0
# git config --global user.name Foo2 Bar - returns 0 and put second name
# cat ~/.gitconfig
[user]
	email = aleksander.baranowski@yahoo.pl
	name = Foo
	name = Foo2
# git config --global user.name Foo - return 5 and message
"warning: user.name has multiple values
error: cannot overwrite multiple values with a single value
       Use a regexp, --add or --replace-all to change user.name."

It's just an opinion, but this behaviour is no consistent for me.

If it's not the bug it's a feature just let me know.

Bests, Alex
