Filesystems behave differently when performing glob listings.
In my environment, they are listed alphabetically. On my Mac, when asking for a list of files in a directory, those files are returned as a nicely sorted list. Alphabetized, like you'd want them to be. Like you'd expect them to be.
In some environments, quite different from my own, the return of a similar operation is quite random. Perhaps q comes before a, or e before d; the filesystem will choose its order of the day and you, the fare user, tired and weary from work, must bare the brunt of this.
And so, with this commit, I do hereby request that the noble makers of Dir provide for us, the downtrodden and ravaged users, some consistency. As a user of Ruby, I shouldn't have to know or consider the behaviour of an individual filesystem here; it should function the same for all filesystems.
