The commented command # now, squeeze all '\n', this can be also done by: # s/^\(\n\)*/\1/
works fine if the hash tag is erased from the second l= ine,
but the next line in the sed script
s/\n*/\ /
that you have left uncommented on your web page adds an extra blank <= br>line after every line. This is not the desired behavior.
