homesick list fails on ruby 2.0.0-rc2, I think because they fixed this
bug: https://bugs.ruby-lang.org/issues/6977, changing the way recursive
globs work. Test case:
```ruby
require "homesick"
require "pathname"
repos = Homesick.new.send :repos_dir
Dir.glob("#{repos}/**/*/.git") # => []
Dir.glob("#{repos}/**/*/.git", File::FNM_DOTMATCH) # => ["/home/eric/.homesick/repos/dotfiles/.git"]
```
This change, however, then broke 1.9.3, but removing the extra "/*"
works on both 1.9 and 2.0.
