If I've understood OP correctly, an empty line implies two consecutive newlines, \n\n.

If so, ondone possible solution would be to eliminate all singular occurrences of newlines.

In Perl, a lookahead assertion is one way to achieve this:

$ perl -0777 -pii -pe 's/\n(?=[^\n])//g' test
  • The -0777 flag effectively slurps the whole file into a single string
  • -p tells perl to print the string it's working on by default
  • -i specifies in-place editing
  • Global matching ensures that all single newline occurrences are dealt with
