I'm using something similar, though I'll probably use your test now
because the expansion isn't always appropriate :)

function magic-dot()
{
    if [[ $LBUFFER =3D *. ]]; then
        LBUFFER+=3D./
        display-path $LBUFFER
    elif [[ $LBUFFER =3D *../ ]]; then
        LBUFFER+=3D../
        display-path $LBUFFER
    else
        zle self-insert
    fi
}
zle -N magic-dot

.. gives ../ so you can use completion without typing the /
... gives ../../
and so on

display-path() prints the target path under the current line, so that
I know where I'm going.
It's a simple trick using xterm control sequences; I don't guarantee
it'll work everywhere but at least it works everywhere I've tested it.

function display-path()
{
    local newpath

    newpath=3D`pwd`/`echo $1 | sed 's_\(.* \)\?\([^ ]\+\)$_\2_'`
    echo -n "\e7\n\e[40m$newpath:A\e[0m\e[0K\e8\e[B\e[A"
}

The only problem I've with these tricks is when pasting paths with
dots in my shell, because ../../foo/bar becomes ../../../foo/bar
