I have never ever heard of any such thing, and I'm very surprised by it. Just
to make sure, did you try a different editor? I could imagine crappy tools
getting confused by inconsistent line endings or such things.

Strange. Is that effect repeatable?

The diff showed the changes you made or the diff showed that the order was
already correct? What does the diff show if you don't change anything, i.e. is
the working copy already modified on checkout? What access method was used on
checkout (file, http, https, svn, svn+ssh)? Could it be that some network
proxy/filter/censorship/firewall application modifies the network traffic?

How exactly? SVN doesn't allow you to check in without changes. What does 'svn
log' on the repository tell you about the created revision?

Wait: You have only had this issue a single time? Can you rule out that some
user or machine accidentally modified the checked out files?

BTW: What is a "baseline"? SVN doesn't use this term, so what exactly do you
mean with it? Also, just to make sure since you have multiple repositories,
you didn't fall for the trap that you created one with svnadmin and the others
by copying? That would give all repositories the same UUID, which messes with
SVN's internals.

Good luck!
