Nice. =C2=A0Let's improve that so that it is possible to specify multiple
files and/or options and files (though we don't give anything but a
single arg special treatment) and also to avoid a "parameter not set"
error for folks that like to run interactively with "setopt no_unset":

vim() {
=C2=A0 =C2=A0 if test $# !=3D 1 -o -r $1; then
=C2=A0 =C2=A0 =C2=A0 =C2=A0 command vim "${@}"
=C2=A0 =C2=A0 else
=C2=A0 =C2=A0 =C2=A0 =C2=A0 local args
=C2=A0 =C2=A0 =C2=A0 =C2=A0 args=3D(${(s.:.)1})
        [[ $#args =3D=3D 2 && $args[2] =3D=3D <-> ]] \
            && command vim $args[1] +$args[2] \
            || command vim $args[1]
=C2=A0 =C2=A0 fi
}
