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

It is not a good practice to prefer performance over readability in 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.

	The original version threatened to cause eye-cancer with this
	developer, so that I had to run to the physician real quick.
	That was quite hard, as no ophtalmologist seemed to be in
	office at 10:30pm.  But I found a real good witch, and she
	diagnozed me as healthy.
