Re: per-buffer language environments

[Per Starbäck]

I've "always" wanted Emacs to know what natural language a buffer is
in, at least text buffers, maybe as a minor mode. Here are two things
I think think haven't been mentioned in the thread yet, which I would
like:

* automatically ispell-change-dictionary
* have language-specific abbrevs

If there's a hook for changing from and to specific languages that
could be used for other things as well, like changing the values of
some sentence-end-* variables.
