I find the patch more readable with --histogram, cut-and-pasted below in
case other reviewers find it better too.

I first wondered why you were not using git_config_get_maybe_bool(), but
you want to interpret non-boolean values as command-names, so you do
need this two-steps get_value -> maybe_bool.
