Option to prefer shorter matches

[tomtom]

When there are multiple matches (e.g. dir X and the subdir X/Y), z X sometimes jumps to X/Y. Sometimes, it would be preferable to have z jump to the shortest match (X in this example).

There's some code in z that does select the shortest match, but only if all matches share the same prefix. So if you you have:

/home/foo/bar
/home/foo/bar/baz

we'll select the first, even if the second is weighted higher. But if you have:

/bar/baz
/home/foo/bar
/home/foo/bar/baz

we just select the highest weight.

I've put a good amount of thought into improvements but I haven't really come up with anything I like better. I'd like to avoid adding flags if possible - keep it simple. In practice, since the arguments to z are regular expressions, I've been able to pretty quickly find a mnemonic (might be a couple arguments) for 'hard to get to' directories like this (for example one machine I share with several coworkers z bin always wants to go to /bin and I always want to go to ~/bin/), once that's in my muscle memory I barely notice it.

I also have a branch that I've been using/testing for a while where order of arguments matter, and I'm this close to merging that to master. It never bothers me, and in situations like this, sometimes helps a lot.

I'll keep this open because I'm not done thinking about this, and am interested in any comments.

Would it be an option to add a command-line option that makes z (1) display a (numbered) list of matching directories if there are more than one, (2) let the users type a number (or set to 0 if there is only one match), (3) jump to that directory? I guess this could resolve all sorts of unintended behaviour.

For the following dirs:

/foo/foobar
/foo

Is it possible that I type z foo and take me into /foo/bar if I am in the /foo/ dir? Or, how about type z foo foo and take me in /foo/bar? The first option is what autojump does, I prefer the second one.
