But this is a bug.  This surely will be fixed one day...

Thank you very much for reporting the bug, I'll file it; it won't be
forgotten.

For now, please don't use -o in combination with -w.
Use \< and \> instead, like this:

        $ echo "dogs dogs and dogs" | grep -o "\<\w\w\w\>"
        and

Hope this helps,
