Thanks, I read the documentation but I am unable to figure out, what
regexp has to be used for that regexp I should use in order to make a
two word expansion work. 

All regexp I tried returned error.

So this 

(define-abbrev-table 'fundamental-mode-abbrev-table
  '(
    ("a que" "a qué" :regexp 1 :count 0)))


Does not return error but does not work as well.

May I suggest to add an example in the documentation of 

`C-h o define-abbrev-table`

Thanks
