.working file not as expected when merging

Hi,

A user reported on the TSVN mailing list a problem when resolving
conflicts after a merge.
I could reproduce the problem, and I think this is a bug in the svn library:

According to the docs (as I understand it), the 'filename.working' file
should be "your file as it existed in your working copy before you
updated your working copy—that is, without conflict markers". But a
simple diff of the 'filename.working' file with the 'filename' file
shows a lot more differences than just the parts with the conflict
markers (even though the file had no local modifications prior to the
merge).

To reproduce this:

$ svn co http://svn.orxonox.net/orxonox/trunk -r3316
$ cd trunk
$ svn merge http://svn.orxonox.net/orxonox/branches/core4 . -c 3270 -r
3271:3276 -c 3279 -c 3281 -r 3284:3286 -c 3288 -r 3289:3295 -c 3306 -r
3309:3311

Now compare the files
src/core/input/InputManager.cc and src/core/input/InputManager.cc.working

I *think* the InputManager.cc.working file is wrong and should not
differ that much from InputManager.cc.

Or is the documentation wrong? Or did I misread/misunderstand the docs?

The problem I have with the .working file in TSVN is that TSVN uses the
.left, .right and .working files to resolve the conflict, not the
'original' file with the conflict markers. And with the .working file in
that state, the conflict resolving leads to a messed up result.

The mail thread of the original report is here:
