You no longer need to make this kind of things to use accented letters for
standard entries under aspell or hunspell, [:alpha:] will be used as
default for them (but not for stuff in `ispell-local-dictionary-alist' where
user choice is honoured).

On the other hand, aspell en.dat only contains ['] as allowed wordchars, 
adding other separators here (in .emacs) may trigger some errors about
different character maps when invoking ispell-word.

aspell seems to internally deal with the explicit acute accent similarly to
', so adding it seems to be OK here.

Apart from that, seems I still get similar results for ispell-buffer and
flyspell with your entry. Please find attached the file I used for tests,
