The number of lstats are cut down by your patch: 428761 vs. 338091.  
Funnily enough, there is no significant difference in run-time:

Command                                            Mean     Std
git status .                                       13.970  1.298
/Users/pieter/projects/External/git/git-status .   13.759  0.321


System times are also approximately the same (10.79s vs 10.43s).
