If you're getting conflicts in those files when performing an update,
then someone *is* using that working copy. Otherwise, the changes
would be merged without conflict into that working copy.

Again, "outside/inside svn" has no meaning (or ambiguous meaning) in
this context - please try to find the correct terminology to use here
to remove this ambiguity. It sounds like your workflow is supposed to

1) Hook developer checks out hook scripts from repository to a local WC
2) Make edits
3) Commit changes to hook script
4) Hook scripts are auto-updated in /svn/hooks via a hook.

Result: Nothing should be in /svn/hooks that isn't in the repository.

What appears to be happening is that someone is editing in /svn/hooks
while at the same time someone else (or maybe the same person) is
editing in their own WC. This can generate a conflict when those
changes are committed from one WC and updated into the other.

Solution: lock people out of making changes to /svn/hooks, except via
that hook script that pulls the updates down. You should not get any
conflicts this way.

Alternate solution: Require people to only make changes in /svn/hooks,
and disallow commits from any other location (which would not be easy,
as the hook script does not know where on the client content is being
committed from - you'd have to do some per-user permissions & only
allowed a specific person/group to commit, and trust them to do the
right thing).

No, part of the point of doing this is to make it *very* obvious that
something needs to be fixed. Even if those lines were commented out,
the content between them would likely break your script, or at least
cause unpredictable/undesired behavior.
