It's not just that. Having many of these in .git/config will slow down
any unrelated thing that needs to read from config.
I am not married to the "reuse existing information" idea, but doing it
the way this sample patch does at least makes only people who uses this
feature to pay the price and only when they use it.
Not extensively tested, beyond the usual test suite, and using it for real
only once to commit this with "git commit --author=Jeff". I wanted to say
"Michael J" instead, but there is this little chicken-and-egg problem ;-)
