Your copy command created a new file, and scheduled it for addition.
The only difference between your copy command and 'touch foo; svn add
foo', is that your schedule-add file has some history attached to it.
The plus sign means it's a 'copy', or an 'add with history'.

I'm surprised this worked... I would have expected an error. I don't
think I've ever seen anyone try to backdate a schedule-add file before!
What's the use case for that?

Ah, interesting. It looks like the 'svn up -r50000' command didn't
error, but it didn't do anything either. The file is scheduled for
addition, which means it has no working-revision in the working copy.
Why? Because it doesn't exist in the repository yet.

As for the display issue: it's possible to have a file that is
schedule-add and locally modified at the same time. But long, long ago,
we decided that printing 'A' has precedence over printing 'M'. There's
only one column to show letters, so we had to choose precedence. Have
no fear, though: when you commit, your file will be created in the
repository by copying from the (Copied-from-URL, Copied-from-rev), and
then your local edits will be transmitted on top of that. So everything
is working expected.
