display the most frequently visited directory but not run `cd`

Created by: xuhdev

Usually, j something switches the working directory. But it doesn't have to. In some cases, we simply need to have the directory printed to stdout. e.g.

open `j --no-cd something`

This could launch the Finder on OS X for the destination directory.

I don't know whether it is hard to hack out this feature, but thanks any way for the great tool!
