I don't know what the server version is. cURL won't accept an svn: URL.
 I can't figure out how to get the version out of the "repro browser",
which is the most direct serverconnection in the toolset I know.

 The answer to that query is "1", so that's the only pattern. (Old
fashioned searches through the dumped list of nodes confirms this.)

Normally I update a large subtree (several levels up from this file).

No, I haven't committed changes from that directory in months. Nobody else
has either.

We moved these files to another repository, so that SVN couldn't (as far as
we could figure out) understand the move. So we renamed the the files on
the source side to keep their history conveniently available.

That is the last revision, and I didn't commit it from this computer. (It

Using the repo browser I can see the whole history. There are just two
versions of this file, none more recent than 3323. I think 3936 is a red
herring -- that was perhaps the tip revision for the whole repository when
the update was attempted. (The current tip is 4013.)

I hate to confess to such absent mindedness, but I may have "svn delete"ed
this file. I see that I don't have a local copy of it, which supports that
theory. If I did that, I didn't commit the change -- the repository still
has the file.

I'm happy to help, and I appreciate your time. Just to be clear, I
wouldn't dream of taking so much of your time just to solve my local
problem. You're digging into this to figure out the bug with change to the
1.7.1 version (or maybe "svn update" within the 1.7.1 version), right?

Since I will likely need to do another checkout anyhow, I'm happy to try
experiments which might be destructive to my local copy.
