Hi Paul,

It sounds like you think the files would remain with read-only

I understood (and implemented, for coreutils) Bruce's proposal
to leave the files with their original -- usually owner-writable --
permissions, yet to add these hints/warning on the first lines:

  -*- buffer-read-only: t -*- vi: set ro:

Then, people with emacs or recent Vi/Vim will be warned before
making changes to the file.  But as I said above, it's trivial
to override these settings.  With recent emacs, you'll be asked
whether to apply the hint (yes, no, or always).  With legacy Vi,
the hint has no effect at all.
