Knittl, I wonder how you generated this patch? Were you working on top
of the "bad" commit?

Strange - I thought I had this sorted out. Thanks for spotting this.

We could do with some parentheses - here's my take:

	fprintf(stderr, "Switched to%s branch '%s'\n",
		(opts->branch_exists ? " and reset" :
			(opts->new_branch ? " a new" : "")),
		new->name);
