Well, I think I had this problem even without editing anything, just by opening and saving a file but I'm not really sure about this. And because this occurs only by some users it must be related to some setting or a combination of settings. Like virtual space behind line endings or syntax highlighting. But this is only an educated guess. And yes, this problem is extremly annoying for years now. A text editor which randomly destroys the files entrusted to it is more or less unusable. No matter how cool its features might be.
