This prints a "createTimestamp:" line on its own block for every 2
consecutive empty lines (in context of the whole program).

Interesting, your description of the solution (sadly not in the

"ahkCreateTimeStamp" line, but implementation above keeps the
"createTimestamp" at its place. So I suppose order does not
