= double newlines, but they'd be in the file.

I think you're saying that the formatting of the text would change
between disk and buffer.  This is an acceptable hack and seems to be the
most promising (most easily implementable) way to go about this.  
Because I'd use paragraph-indent-mode after the file's first ~30 words,
format-alist shouldn't have a difficult time understanding what the file
is supposed to be.

= In order to see double newlines, I would if it might work to use
= something similar to font-lock to place overlays on every newline with
= a before-string or after-string property containing one or two
= newlines.  I never tried, so I don't know if it works.

I've used font-lock, but never poked around in the code for it.  Doing
that for this sort of file format would get pretty tricky-- at least for
an elisp neophyte like myself.  But it sounds-- on the face of it-- like
it would address the issue at the level of coding where it should be
addressed-- at least insofar as emacs can address it.


= Hm.  I guess it would be really difficult to change Emacs in such a
= way that M-q and friends and auto-fill do what you want for
= double-spaced files.

I've done enough C to say that writing the code to do the work of
fill-region in double-line-spacing wouldn't be too hard at all.
Unfortunately, the C code for such a function would be worthless for
emacs (yes?).  Getting the double-line-spaced text to snake down and up
the page as editing added and deleted text would involve essentially the
same code, but invoked after every text-insertion and -deletion.  Still
not a huge mountain to climb-- but still useless to emacs if done in C 
(or so I'm guessing).



= Hm.  Isn't there a way to tweak the distance between baselines in
= Emacs?  That would enable people to have the look of double-space
= without actually having two consecutive newlines in the buffer.  Then
= format-alist could add the newlines to the files.

Poking around in the code, I found a variable for this, called
dbl-space, But this is a non-solution.  Simply having the text look like
it's double-line-spaced would be of no use.  Once completed, the
manuscript file would either be printed and snail-mailed or directly
emailed to an editor (the human kind).  This ultimate destination is
where the formatting actually matters.  And in either case, the line
spacing would be lost in the transition.


Kai,

Thanks much for your reply and suggestions.  I hope that, despite the
difficulties, it's still possible to make something come of all this.
