I horsed around with the 'N' command in sed, thinking I could make it
do that, and figured out that I had lost the sed touch.  (Somebody
will most certainly post the proper way to do it.)  Try

tr '\012' ' '

instead of sed.  If you really need the trailing newline, and you have
a shell with a builtin echo, try:

...some_command |
some_command_that_produces_those_lines |
while read x
do echo -n "$x "
done
echo ""

or

echo `some_command_that_produces_those_lines`

depending on how you get your data.  The first one is *really*
expensive if you don't have a builtin echo, but the second one isn't
bad.

Obligatory Perl reference:

perl -pe 's/\n/ / unless eof;'

Just another (former) sed user,
