Ooh, I did not know that. Thanks. Is this documented somewhere? (I.e., a
recommendation that a major mode function should be called in any buffer
of potential interest to the user.)

In that case, `after-change-major-mode-hook' should do, after all.

Yes, I admit I have code around that does(n't do) that myself (e.g.
simple dumping of some text into a buffer left in fundamental-mode), as
I had no idea calling e.g. `fundamental-mode' in a buffer already in
fundamental-mode was supposed to be of some value (until I bumped into
this problem, that is).
