Just a nit: Your example is misleading because it "only" shows that if you
shove in junk, and ask for junk, you get breakage. However, the breakage
is much more serious, and you could have demonstrated it, if you had
written your example like this:

$ git config .foo false
$ git config user.email
fatal: bad config file line 6 in .git/config

Not a nit: These tests only show that 'git config' cannot be asked for
junk, but they do not show that you cannot insert junk into the config
file anymore using 'git config'.
