Closing based on this:

> Having looked into it some more, I'm not 100% convinced it's a bug
> any more.  Here's why:
>
> `expand-abbrev' may run arbitrary code, and some abbrevs don't just
> replace text with something else but also prompt and/or move point
> (e.g. skeletons).  So running expand-abbrev from
> visual-basic-newline-and-indent just doesn't sound right since it may
> conflict with user-defined abbreviations.
>
> I.e. the problem you're seeing can also happen in Emacs-22 depending on
> the user's own abbreviations.  So the VBM code either needs
> a save-excursion, or needs to refrain from calling expand-abbrev from
> visual-basic-newline-and-indent.
