I read the documentation for ispell-dictionary-alist more carefully, and
came up with:

 '(ispell-local-dictionary-alist (quote (("british" "[[:alpha:]]"
"[^[:alpha:]]" "['’]" t ("-d" "en_GB") nil utf-8))))

where I made the "others" character set a character class.

I checked the aspell command actually being run (with "ps") to ensure that
it is indeed using "-d en_GB", and if I change the second argument to the
(bizarre) setting of "fr_FR", this is used, so my settings in
ispell-local-dictionary-alist are being used. If I run
ispell-get-otherchars, I get

['’]

as expected. If I run "(looking-at (ispell-get-otherchars))" while sitting
on a curly quote, I get:

t

Actually, now I see something weird is happening. I type:

"didn’", i.e. "didn" followed by a curly quote, and the word is highlighted
as misspelt. If I then type "t" to finish the word, it is unhighlighted,
after a pause.

Is there some other part of flyspell that is more rough-and-ready which I
also have to tweak?
