Yes, this one's pretty good, though I suspect the actual reason for the patch is not just dead code elimination.

The patch itself gives reason to be comfortable: the "while" loop right after the removed "if" checks the value of *p immediately, so if callers start passing NULL, it will be pretty obvious.

I suspect the actual motivation is to avoid access to the "commit" global, in preparation for making it local. A nice side-benefit is removing a translated message.
