change in fill-paragraph

[ken]

With the versions of emacs I've been using for years, fill-paragraph 
won't fill/reformat include in its definition of a paragraph any line 
which begins with a space.  However, the newer emacs version I use at 
work will.  That is,

(1) In the older versions, this will be
one paragraph.  M-q will reformat it
fine.  I like it this way.
 (2) In the older versions, having just a
single space at the beginning
of a line tells paragraph-fill that this is
a separate paragraph.  So this would be a
separate paragraph.
 (3) In the new emacs version, all of these
would constitute one paragraph and so be
filled together.  I would much prefer the older way
fill-paragraph works... so that (1), (2), and (3)
stay where they are.

How would I restore the old behavior to the new version of emacs?


Thanks much.
