Steve, if you follow Jan,s script above, you will see that the file
foo.txt that the user created with the contents "goodbye" was deleted
by Subversion without notification. That is, by definition, data
loss, and Subversion should not do that. (There are many places where
texts claim that Subversion will not lose your data.) Jan, this
sounds like a bug, and if it's not already submitted, I would
recommend submitting it.
Yes, unfortunately, to submit a bug, you must not only register at
tigris, then also request observe rights for the subversion project.
I hope you will do this and submit the bug, so that the problem is
recorded in the database and it has a hope of getting fixed.
