Good point. I sure didn't!

I think the docs are confusing on this. The section on "The
Limitations of Mixed Revisions", which I had read a couple of times,
makes it sound like it's a bit out of the ordinary to have mixed
revisions. It may be odd in the world of VCS's generally, but for
Subversion it is probably the normal state of a WC and that would be
worth mentioning. It is described as a "special flexibilty" and not as
the routine condition.

The issue then is the definition of "working revision". I would have
called the "working revision" r6 in your example, but I see it can be
defined either way.

What switch (if there is one) means "run the subcommand on a default
target of CWD at the most recent revision which has a committed change
to CWD"?

What exactly is getting updated when you do an svn update and nothing
has actually changed except the single file you just committed? Is it
just the revision number in .svn/entries?

Thanks,
