[PATCH v3 0/3] Introduce log.showSignature config variable

Add a new configuratation variable "log.showSignature" for git-log and related commands. "log.showSignature=true" will enable user to see GPG signature by default for git-log and related commands.

Changes compared to v2:
	* A preparatory patch 1/3 has been introduced so that tests
	  in patches 2/3 and 3/3 can take advantage of it.
	* Mistake regarding branch in [patch v2 2/2] has been
	  corrected.
	* Tight coupling between the tests in [patch v2 2/2] has
	  been resovled.

I would like to thanks Eric Sunshine for his feedback on previous series [1].
