Style question

[Scott Kostyshak]

Regarding the following code:

-----
void Text::selectWord(Cursor & cur, word_location loc)
{
  LBUFERR(this == cur.text());
  CursorSlice from = cur.top();
  CursorSlice to = cur.top();
  getWord(from, to, loc);
-----

It is not easy to know whether "to" and "from" are equal to each other because
cur.top() might return something different the second time. For readability
purposes, I would prefer either

  LBUFERR(this == cur.text());
  CursorSlice from, to;
  from = to = cur.top();
  getWord(from, to, loc);

or 

  LBUFERR(this == cur.text());
  CursorSlice from = cur.top();
  CursorSlice to = from;
  getWord(from, to, loc);

Does anyone else have a preference?
