Force Git to set e-mail address in working copy
It may be my personal quirk, but I really dislike that Git pulls an email address from global config unless you override it on per-repo basis. Or worse, makes up an email address from
whoami or whatever. I just learned that there is a config option to make it stop doing this.
git config --global --unset user.email git config --global user.useConfigOnly true
Now email addresses have to be set on a per-repo basis.
