IMO it does describe the transition (otherwise we'd have E for
Exists instead of A for Add, etc. A given revision describes
how to get from rev A to rev B inclusive. Hell, when you ask
svn to update your working copy to a new revision what you are
*actually* doing is not pulling the complete state of the target
revision but rather you are pulling the *transition* instructions
required to get you there (the diff that gets applied).
If r33 described the state of repo at r33 the log entry would
show you every file that *does* exist. But it doesn't do that,
no, rather it shows you what files *must be removed* in order
to get there. IOW it shows you the *transition*.

It is invalid to consider the removal of an object to be of no
historical relevance to that object.

However you want to describe it, it's part of the object's history.
A query for that history should display it. *Not* displaying
one of the most important historical events that can happen to
an object is invalid.

Show me a sane way to retrieve the full history of an object
and I'll shut up. Until then I'm being more then kind by
only claiming svn is broken. Seriously, we are talking
about a historical database that is flatly *incapable* of
providing the complete history of an element without
requiring the user to jump through a maze of complex hoops.

Again, show me a sane way to retrieve an object's complete
history and I'll drop the subject.
