The only way not to have the LF/CR is to use MIME/Quoted  Printable.
You can set the length of the line before the LF/CR in tools\ Options | Send

I think most of your problems are being caused by using a line length
of 132.    As it happens that is what I use too but it means that I always
have to manage line-ends myself, just as if I was still using a typewriter
or dumb terminal.

Just to show you how it works, I am leaving your long lines exactly
the way that  Ctrl-g  gave them to me.   Normally I would re-edit
such quotes so that my use of 132 wouldn't be exposed that way.

In fact,  XPsp2  has caused a new related problem for me with its
X-RFC2646: Format=Flowed; Response   header.
E.g. even if you had used a more normal sized line length
the Format=Flowed feature with *my* line length would have
reformatted my quotes from *your* short lines into my *long* lines
*after* I sent my reply.    In order to deal with this I have to consistently
examine the Properties of each reply in my Outbox, checking if the above
header is present.  When I find it I have to reopen the message and
replace the unwanted formatting with what I originally wrote.
This happens often enough that I have developed a regular procedure
when posting online:   Ctrl-a,Ctrl-c,Alt-F,W,Alt-S.    Provided I don't
accidentally change the contents of my Clipboard before finding
that I need to fix the reply I can do that easily by opening it,
selecting it all, and pasting the old contents over the selected.
E.g.   Ctrl-a,Ctrl-v.    Fortunately, the Format=Flowed; Response
header then changes into a  Format=Flowed; Original  header
and my formatting is thus left alone.
