1) It is not possible to represent svn move operation in an unified diff format. Adds are represented (as a new file with content vs. old file of zero length), but there is no information about where the file was copied from. 2) Patches are applied by an external program. Implementations do differ. As someone noticed, there is an ambiguity, whether the file was deleted or whether its content was removed (setting its length to 0). Also patch carries no explicit information about creating intermediate directories if those are needed. 3) In complex cases I used to provide/propose not only a patch file, but also a series of commands that are to be executed before applying it. The Subversion 1.7 (that is currently being developed) is expected to solve 1) and 2) by providing enhancements to the diff format generated by subversion (I am looking forward to "svn diff --git" option) and new "svn patch" command. http://subversion.apache.org/roadmap.html http://svnbook.red-bean.com/nightly/en/svn.ref.svn.c.diff.html Regarding BZ 50001, note that *.launch files have already been moved and renamed in the current /trunk.
