I noticed this bug because it breaks expanding abbrevs at the beginning
of the line.  E.g. you've just pressed 'R' to reply with quoting the
original message in Gnus, and point is at the beginning of the first
quoted line.  Then if you type a word that is the key for an abbrev, and
then whitespace, it won't expand.  I wonder if that can be fixed without
losing the benefits of João's change.
