Having said all that, here is a tip of the day.  I have this in my .bashrc
for interactive shells.

        cdup () {
                local eh
                eh=$(git rev-parse --is-inside-work-tree) || return
                case "$eh" in
                true)
                        eh=$(git rev-parse --show-toplevel)
                        test -z "$eh" || cd "$eh"
                        ;;
                false)
                        eh=$(git rev-parse --git-dir) || return
                        cd "$eh" || return
                        eh=$(git rev-parse --is-bare-repository) || return
                        test "z$eh" = ztrue || cd ..
                        ;;
                esac
        }

and I can say

	$ cd Documentation/howto
        $ editor *.txt
        $ cdup

to come back to the toplevel after having worked somewhere deep in the
mine.
