I've run into this, too. I've checked one occurrence of this in the hex editor view. The original byte sequence looked like 75 6C 6C 70 74 72 3B 0A 20 20 20 20 7D 0A 20 20, and it turned into 75 6C 6C 70 74 72 3B 0A _FF 00_ 20 20 _10_ 0A 20 20.
Likewise, that line was nowhere near any edits of mine. -- <https://forum.pspad.com/read.php?4,77267,77397> PSPad freeware editor https://www.pspad.com
