This is the sixth version of a patch series that implements the GSoC microproject of converting a recursive call to readdir() to use dir_iterator.

The only suggestion that did not make it into this series was that of not traversing into subdirectories, since I believe it would be better off in another series that actually required that feature (that is, I do not want a series to implement a feature it will not need). The same goes for Junio's thought on a flag to list *only* directories and no files on the v4 discussion. Junio and Peff's comments about how to write to files in the tests were also considered, and the tests were adjusted. I chose to squash both the state machine refactor and the addition of the new flags in a single commit. I do not know whether you will feel this is the right choice but it seemed natural, since most of the state machine's new logic would not even make sense without encompassing the new features. I am, of course, open for feedback on this decision. To Michael and Duy, thanks -- really -- for the encouraging comments! :) I never regarded this microproject purely as a means to fulfill a GSoC requirement, but as a way to get to learn more about Git, so I'm surely not giving it up. Once again, thanks for all the previous reviews, Daniel.
