After looking at this again, there's still no difference between nil
and \\sw\\|\\s- AFAICS, but now dabbrev--abbrev-at-point makes little
sense to me:
emacs -Q --eval '(setq dabbrev-abbrev-char-regexp "\\sw")'
in scratch:
yes-or-no---
followed by M-/ gives
"No dynamic expansion for `no---' found". Obviously, "---" are not
word constituents, yet they are included in the abbrev, in flat
contradiction to the doc-string of dabbrev-abbrev-char-regexp:
if you set this variable to "\\sw", then expanding `yes-or-no-'
signals an error because `-' is not part of a word
This is caused by dabbrev--abbrev-at-point's:
;; If we aren't right after an abbreviation,
;; move point back to just after one.
;; This is so the user can get successive words
;; by typing the punctuation followed by M-/.
