merge(3p/git): Merge git subtree at v2.29.2 r/1890

This also bumps the stable nixpkgs to 20.09 as of 2020-11-21, because
there is some breakage in the git build related to the netrc
credentials helper which someone has taken care of in nixpkgs.

The stable channel is not used for anything other than git, so this
should be fine.

-	    Hope, he says, cherishes the soul of him who lives in
-	    justice and holiness and is the nurse of his age and the
-	    companion of his journey;--hope which is mightiest to sway
-	    the restless soul of man.
-
-	How admirable are his words!  And the great blessing of riches, I do
-	not say to every man, but to a good man, is, that he has had no
-	occasion to deceive or to defraud others, either intentionally or
-	unintentionally; and when he departs to the world below he is not in
-	any apprehension about offerings due to the gods or debts which he owes
-	to men.  Now to this peace of mind the possession of wealth greatly
-	contributes; and therefore I say, that, setting one thing against
-	another, of the many advantages which wealth has to give, to a man of
-	sense this is in my opinion the greatest.
-
-	Well said, Cephalus, I replied; but as concerning justice, what is
-	it?--to speak the truth and to pay your debts--no more than this?  And
-	even to this are there not exceptions?  Suppose that a friend when in
-	his right mind has deposited arms with me and he asks for them when he
-	is not in his right mind, ought I to give them back to him?  No one
-	would say that I ought or that I should be right in doing so, any more
-	than they would say that I ought always to speak the truth to one who
-	is in his condition.
-
-	You are quite right, he replied.
-
-	But then, I said, speaking the truth and paying your debts is not a
-	correct definition of justice.
-
-	CEPHALUS - SOCRATES - POLEMARCHUS
-
-	Quite correct, Socrates, if Simonides is to be believed, said
-	Polemarchus interposing.
-
-	I fear, said Cephalus, that I must go now, for I have to look after the
-	sacrifices, and I hand over the argument to Polemarchus and the company.
