safeguard: add an option to disable automatic publishing
Pushing to publishing server by mistake is a bit too common in the current state
of evolve. Especially when the lack of good feature branch story make the use of
-f a bit too common.
So we add a very simple experimental option to allow warning (or abort) when
changeset are pushed to a publishing server. This is unlikely to survive as is,
but this is useful now.
# Code dedicated to adding various "safeguard" around evolution
#
# Some of these will be pollished and upstream when mature. Some other will be
# replaced by better alternative later.
