After playing a bit more: if I scroll through entire file before I
enable my mode, then entire file is processed correctly. But if file is
not scrolled through, then only 3½ screen pages are processed. Has
nothing to do with regex I use, just with text being shown on screen or
not. I don't find anything in docs about that. A bug? Or undocumented
behaviour? Or something else I am missing here?
