I have always had trouble with newlines and sed.  The way I
would deal with your problem is to use 'tr' and then sed.
It would go something like this:

tr "\012" "#" < datafile | sed -e 's/#/, /g' > outfile

This translates all new lines to a printable ascii character.
You should use one that does not occur elswhere in the file.
The output is piped to sed where the character '#' is expanded
to ', '.  

I, too, would like to see a sed example doing the whole
process.
