Here's my quick'n'dirty code:

relate()
{
    local -a what to res

    what=( ${(ps:/:)"${${${${1//\/\///}//\/.\///}%%/.}%%/}"} )
    to=( ${(ps:/:)"${${${${2//\/\///}//\/.\///}%%/.}%%/}"} )

    while (( $#what > 0 )) && (( $#to > 0 )) && [[ $what[1] == $to[1] ]]; do
	what[1]=()
	to[1]=()
    done

    while (( $#to > 0 )); do
	res+=..
	to[1]=()
    done

    res=( "$res[@]" "$what[@]" )

    echo ${(pj:/:)res}
}

relate Completion/Unix/Command/_git Functions/
