[RFC PATCH 0/3] editor: teach it to protect itself from rogue editors

["Carlo Marcelo Arenas Belón" <carenas@gmail.com>]

This series reimplements a problematic series that was partially
reverted in 2.34.1, but addressing all raised concerns and being
a lot more conservative.

The first commit addresses directly the issue reported and that
required the revert, but punts several changes to future series
to make sure it is safe enough for backporting into maint if
needed, it also tries (probably too hard) to not introduce any
behaviour changes, so it might seem "incomplete", but expect
further changes that will clean it up further.

The the second one is taken from a draft[1] and is ammended by
the third, hence why this is all still an RFC.
