Gaaak!  Let me again plead for supporting a post-clone hook rather than
inventing some crazy config-file syntax that is becoming ever more
complicated.  A post-clone hook would make all of these things that have
been suggested pretty easy, and would also open lots of other
possibilities, all without further changes in git.core, like (I'm just
brainstorming here):

    #! /bin/sh

    remote="$1"

    ln -s $(HOME)/.githooks/* .git/hooks

    case "$(git --version)" in
    *.1.[78].*)
        git config include.path "$(HOME)/.gitinclude
        ;;
    esac

    echo "(cd $(pwd) && git gc)" >>"$(HOME)/cron.weekly/git-gc"

    case "$remote" in
    *.work.com/*)
        git config user.email me@work.com
        ;;
    *.github.com/*)
        git config user.email me@debian.org
        ;;
    *)
        echo '### Remember to set user.email ###'
        ;;
    esac
