Sure. You are an advanced user of git. Is that a problem to see help text intended
for others? The help text would be targeted to those who are not advanced
users of git, and yet have some pre-existing hooks for whatever reason. Novice
users will not have the hook. Advanced users will incorporate the hook themselves.

The autogen.sh script (or whatever) can check if the pre-existing hook is a link
into the ofi source and then not offer the help text.

Right .. but doesn't the development process require the maintainer to merge
and/or perform pull requests before code gets in to master? Only a select few
can push to master, right?
