[Github-comments] [geany/geany] Filetype is not redetected on reload, even when current filetype is None (Issue #2996)

Not a good presumption.  Most mentions of filetype in the manual are related to modifying the default behavior.

Not that rare.  Most of the geany-plugins README files are "detected" as None.

I did not find this "filetype guarantee" in the manual.  It is a 74-page document, so maybe I missed it.

Since "None" is the fallback filetype, it's a good candidate for another detection attempt.  Always auto-detect on reload would also be reasonable because reloads are forced by the user or external changes.
