Crash with the symlink command

[nickserv]

This may have been caused by some of our recent refactoring work. In case you're curious, I'm currently on 41f3f9d and I'm using https://github.com/nicolasmccurdy/dotfiles for testing.

This is not an issue on v1.0.0. I'm going to try using git-bisect on this.

[JCook21]

@nicolasmccurdy can you write a spec test that fails? That should then make it easier to work on this issue with git bisect.

[nickserv]

I was originally just going to try running homesick symlink manually or with a bisect script, but I think it would be a great idea to write regression tests for this. I'll hopefully have a pull request ready, and a fix if I figure it out soon.
