[PATCH 1/2] git wrapper: Make while loop more reader-friendly

something as performance uncritical as finding the trailing slash
of argv[0].

So avoid head-scratching by making the loop user-readable, and not
hyper-performance-optimized.

	office at 10:30pm.  But I found a real good witch, and she
	diagnozed me as healthy.
