Hi,

I call dabbrev-expand while the minibuffer is active (e.g.,
interactively calling eval-expression), it dabbrev hangs in
dabbrev--goto-start-of-abbrev.

The reason is that (bobp) is false and (forward-char -1)
can't backup into the prompt.

I'm thinking advicing bobp to cope with this, but is there a
better fix?

I'm using emacs 21.3.

Thanks.
