I am not entirely sure, I understand the logic behind this. To give you
a concrete example. (That enters now the flyspell problem).

I have defined for each language I use flypsell/ispell a minor mode and
a corresponding local-abbrev table.

    1. American

    2. British

    3. German

    4. Spanish

    5. French

    6. And even Hebrew (but we can leave that may out for the moment).

Now say I am in latex mode and turn spelling for American on (which in
turn turn the minor mode american-spelling on), is then the local abbrev
table the first in that list?
