And I cannot tell why placing the burden of determining primacy on the
server hook solves the problem in any way either. Some process still
has to determine which competing log-template gets used; by punting
completely, you place *all* of the burden on the site admin to take this
[possibly marginal in real life] use-case into consideration when
writing the hook script.

Here's a couple of ideas for dealing with conflicts (straight from my
brain to your eyes, no thought to complexity of implementation):

1) Highest One Wins - the template in force for the shortest path that
contains all committed file paths.

2) To Each His Own - If those 20 files are covered by 3 log-templates
(for example), then the client splits the commit into 3 seperate
commits, each with it's own custom template. We should be able to
assume that if a site has that many templates scattered about their
tree, then that should be taken as a significant factor and we should
respect the effort and not impose a single template.

Of course, in both cases a --no-log-template switch to the client should
shut off all special processing and lead to the existing "dumb"
template. Any site wishing to require specific formatting has to use
the pre-commit hook to validate the text anyways.
