Are you sure?  In C code, I see exactly 2 calls to 'widen' and 4 calls
to 'narrow-to-region', something that doesn't really fit "all the time"
description.  (Most of the above few calls are to support auto-saving
and process-filters, and the rest are in set-buffer-multibyte -- it
should be clear to anyone that all of the above must override any
narrowing.)
