Don't worry too much about it. Consider it something to keep in mind for
future patches. I reviewed the change and it seemed okay. I mentioned it
because one of the goals of patch submission, in addition to making an
actual change, is to ease the review process. If Junio is okay with
accepting it as is, then it's probably not worth spending more time
trying to refine it.

Having said that, I came up with the following for those two paragraphs,
which gives a much less noisy diff and doesn't look too jagged:

--- 8< ---
 If conflicts arise and a strategy for automatically resolving
-conflicting notes (see the -s/--strategy option) is not given,
-the "manual" resolver is used. This resolver checks out the
+conflicting notes (see -s/--strategy or notes.merge configuration) is
+not given, the "manual" resolver is used. This resolver checks out the
 conflicting notes in a special worktree (`.git/NOTES_MERGE_WORKTREE`),
 and instructs the user to manually resolve the conflicts there.
 When done, the user can either finalize the merge with
--- 8< ---

...and...

--- 8< ---
 	When merging notes, resolve notes conflicts using the given
-	strategy. The following strategies are recognized: "manual"
+	strategy. Overrides the "notes.merge" configuration variable.
+	The following strategies are recognized: "manual"
 	(default), "ours", "theirs", "union" and "cat_sort_uniq".
 	See the "NOTES MERGE STRATEGIES" section below for more
 	information on each notes merge strategy.
