Boxxy creates and deletes all targets at once

[mesaprotector]

Could be a duplicate of #228 but I'm not sure.

I'm trying out boxxy and have it set for six applications, all of which run fine with it. But what seems to be happening is that boxxy creates all six of the target directories when one application is run through boxxy, and then deletes all six of them when a program exits, instead of just creating and deleting the single one for the relevant program.

This causes problems if I have more than one boxxed application running at once - closing Firefox also deletes .golly even though it's still in use, and it complains about not being able to save preferences.

I'll look into the code myself but the most difficult programming task I've ever done is writing a 40-line R script.

Actually I think it was just my fault not understanding how the "only" field worked and now I feel silly. Spent an hour reading through mod.rs and kind of get what it does now.

I do think "boxxy scan" needs some work; aside from mixing up file/directory it also suggests "Only: []" by default, which causes the above issue. Closing.
