Why make this command kill local variables?
Most buffer-local variables come from the major mode.
Is it really desirable to reliminate the major mode?

Eliminating the major mode is what `fundamental-mode' does.
Text properties are usually related to the major mode,
often due to Font Lock mode.

Should `fundamental-mode' eliminate text properties?  Or perhaps only
some text properties?

Should `clean-buffer' eliminate only the text properties and overlays
that do NOT come from the major mode?
