Hmm, in this case, git-merge.txt may need an update as well. From
'dl/merge-autostash', 

	'git merge --abort' is equivalent to 'git reset --merge' when
	`MERGE_HEAD` is present unless `MERGE_AUTOSTASH` is also present in
	which case 'git merge --abort' applies the stash entry to the worktree
	whereas 'git reset --merge' will save the stashed changes in the stash
	reflog.

and

	--quit::
		Forget about the current merge in progress. Leave the index
		and the working tree as-is. If `MERGE_AUTOSTASH` is present, the
		stash entry will be saved to the stash reflog.

both need to be amended to remove the reference to the "stash reflog".

When I was writing this documentation, I wanted to distinguish between
the temporary autostash entry and the actual stash since the autostash
entry isn't pushed to the stash unless there are conflicts or it's
explicitly saved. I'm not sure that something like "If a temporary stash
entry was created using --autostash, it will be stashed away" works very
well since the word "stash" is overloaded here to mean "a random stash
commit" and "stashed away in _the_ stash". Unfortunately, I'm also
having trouble coming up with a suitable phrasing of my own.

I dunno, perhaps I'm overthinking this too and your suggested rewording
sounds good and I'm just being too picky.

Thanks,

Denton
