My simple function `asug-get-previous-words' function performs quite well,
it seems. I could not get `looking-back' to work across lines. It was very
quick
though, when words was on the same line.

Also, collecting all active abbrev expansions was also very fast (1000 runs
takes 0.1 on my not very hot PC) so I did not bother with that
optimization. But
perhaps I will experiment a bit with that too.

All in all this seems to turn out quite nicely. I will try to integrate it
properly in
abbrev.el and add some option there to toggle this feature on.

Thanks for the pointers!
