That's an implementation detail.

That's *extremely* dangerous advice. If you open one of those files in
a text editor, you run an extremely high risk of corrupting your
repository, quite possibly creating a latent corruption that will only
manifest months or years later.

Don't ever edit those files. If you're curious, use a sandbox, or an
svnsync mirror, and play with that.

Don't bother trying. It's not possible to edit a revision file without
corrupting the repository.

svnwcsub, documented in the FAQ.

P.S. Geoff: don't let the above discourage you from understanding how
svn works behind the scenes. The only thing I ask is that you don't
give people advice that effectively teaches them how to corrupt their
repositories....
