Merge builtin-stash-rebase-v2

Browse Source 
This trick was performed by rebasing the builtin-stash-rebase branch
thicket via `git rebase -kir v2.19.0-rc2`, replacing all branches that
made it into `pu` by their current versions (and also the builtin-stash
by the newest iteration as of ungps/git), and then calling these
commands:

	# save current tip
	tip=$(git rev-parse HEAD)

	# revert previous merge
	git reset --hard git-for-windows/master^0
	git revert -n -m 1 HEAD
	git commit --squash HEAD -s -m "Let's drop this"

	# now perform the 3-way merge with v2.19.0-rc2 as base
	git merge-recursive v2.19.0-rc2 -- HEAD $tip
	git merge --ff-only \
		$(git commit-tree -p HEAD -p $tip -m "Merge" \
			$(git write-tree))
	git commit -c HEAD^^ --amend -s

The merge-recursive dance is necessary because of the merging-rebases:
the fake merges with which these start are mistaken by `git merge` to
mean that the branches were already merged, when the fake merges undid
the corresponding changes.
