+;;
+;; Undo in region is a use case that requires adjustments to undo
+;; elements. It must adjust positions of elements in the region based
+;; on newer elements not in the region so as they may be correctly
+;; applied in the current buffer. undo-make-selective-list
+;; accomplishes this with its undo-deltas list of adjustments. An
+;; example undo history from oldest to newest:

+;; --------- ---------------- -----------

+;; aaba (3 . 4) N/A (in region)
+;; ccaaba (1 . 3) (1 . -2)
+;; ccaabaddd (7 . 10) (7 . -3)
+;; ccaabdd ("ad" . 6) (6 . 2)
+;; ccaabaddd (6 . 8) (6 . -2)
+;; | |<-- region: "caab", from 2 to 6
+;;
+;; When the user starts a run of undos in region,
+;; undo-make-selective-list is called to create the full list of in
+;; region elements. Each element is adjusted forward chronologically
+;; through undo-deltas to determine if it is in the region.
+;;
+;; In the above example, the insertion of "b" is (3 . 4) in the
+;; buffer-undo-list. The undo-delta (1 . -2) causes (3 . 4) to become
+;; (5 . 6). The next three undo-deltas cause no adjustment, so (5
+;; . 6) is assessed as in the region and placed in the selective list.
+;; Notably, the end of region itself adjusts from "2 to 6" to "2 to 5"
+;; due to the selected element. The "b" insertion is the only element
+;; fully in the region, so in this example undo-make-selective-list
+;; returns (nil (5 . 6)).
+;;
+;; The adjustment of the (7 . 10) insertion of "ddd" shows an edge
+;; case. It is adjusted through the undo-deltas: ((6 . 2) (6 . -2)).
+;; Normally an undo-delta of (6 . 2) would cause positions after 6 to
+;; adjust by 2. However, they shouldn't adjust to less than 6, so (7
+;; . 10) adjusts to (6 . 8) due to the first undo delta.
+;;
+;; More interesting is how to adjust the "ddd" insertion due to the
+;; next undo-delta: (6 . -2), corresponding to reinsertion of "ad".
+;; If the reinsertion was a manual retyping of "ad", then the total
+;; adjustment should be (7 . 10) -> (6 . 8) -> (8 . 10). However, if
+;; the reinsertion was due to undo, one might expect the first "d"
+;; character would again be a part of the "ddd" text, meaning its
+;; total adjustment would be (7 . 10) -> (6 . 8) -> (7 . 10).
+;;
+;; undo-make-selective-list assumes in this situation that "ad" was a
+;; new edit, even if it was inserted because of an undo.
+;; Consequently, if the user undos in region "8 to 10" of the
+;; "ccaabaddd" buffer, they could be surprised that it becomes
+;; "ccaabad", as though the first "d" became detached from the
+;; original "ddd" insertion. This quirk is a FIXME.
