Thanks, Peter, Lennart for your answers annd sorry for my chaos.

On digging deeper, it was actually a *minor* mode trying to set up the
visual-lines mode (I wrote that code. Should have known. Onset of
senility? Sorry for that).

I'll try to debug things a bit further and come back.

Yes, I gather this from the doc. That's why I was surprised. What brogut
me to the conclusion that someone was wiping away the mode (local)
variables was that declaring visual-line-mode 'permanent-local shows up
the mode lighter in the mode line (of course the visual-lines mode
doesn't work properly, since it probably has lost some vital parts on
the way).

Might still hold for a minor mode. As far as it concerns major modes,
I'll take it back. Shame on me and sorry for the noise.

I'll report on my findings.

Regards
