Then one needs to customize ispell-local-dictionary-alist to include
the setting for en_US.  Here's what I have there:

     '("en_US"
        "[[:alpha:]]"
        "[^[:alpha:]]"
        "[']" nil ("-r") nil utf-8)

The OP may wish to omit the -r switch, it's not a necessity.

Also, be sure to look at en_US.aff and match the character set it
mentions there with the "utf-8" part above.
