sed - match newlines on input (Oops+Fix)

>>      s/one\ntwo\nthree/one, two, three/g

The previously posted examples fail for:
	...	OR	...
	abc		abc
	abc		123
	123		abc
	xyz		123
	...		xyz
			...

# A "better" approach might be:

sed -n "
       :top
       /^abc$/{h; n
               /^123$/!b top
                      {H; n; /^xyz$/!b top
                       H; g; s/\n/, /gp;}
              }" ${*:-}
