subversion merging changes renamed files?

i have following problem controlling subversion:

i'm now operative box digest plan refactoring (which includes renaming files relocating files opposite directories).

at same someone else operative same digest branch.

at i wish combine changes finished bend behind trunk. includes changes finished files (on branch) have renamed trunk.

i tests seems presumably overthrow able following changes i'm blank someting (which i wish for). i tested controlling following book (should work bash, assumes an svn repository during ""):

svn co http://myserver/svn/sandbox

cd sandbox/

mkdir -p myproject/trunk myproject/branches myproject/tags

cat - <<eof >myproject/trunk/fileone.txt
test
1
2
eof

svn supplement myproject

svn dedicate -m "init"

# emanate branch
svn duplicate http://myserver/svn/sandbox/myproject/trunk http://myserver/svn/sandbox/myproject/branches/branch_1 svn duplicate http://myserver/svn/sandbox/myproject/trunk http://myserver/svn/sandbox/myproject/branches/branch_1

# rename file
svn pierce myproject/trunk/fileone.txt myproject/trunk/filetwo.txt

svn dedicate -m "renamed file"

svn transform 

# change calm fileone branch

cat - <<eof >myproject/branches/branch_1/fileone.txt
test
2
3
eof

svn dedicate -m "changed branch"

# i try combine changes fileone behind filetwo
cd myproject/trunk/
svn combine -r1:head http://myserver/svn/sandbox/myproject/branches/branch_1
# nonetheless yields following message:
# skipped blank target: 'fileone.txt'

any assistance severely appreciated.

edit:
perhaps slight suggested mikegrb rather involuntary initial generating map renamed files (old->new) svn record management trunk:

svn record -v
------------------------------------------------------------------------
r33 | sme | 2008-10-09 15:17:54 +0200 (do, 09 okt 2008) | 1 line
changed paths:
   d /myproject/trunk/fileone.txt
   /myproject/trunk/filetwo.txt (from /myproject/trunk/fileone.txt:31)


resulting map: {fileone.txt => filetwo.txt}

now map change filenames patch record generated branch.

original:

index: fileone.txt
