Description

svn diff is not usable to generate patches between revisions that either add or remove files.
Added files must have /dev/null as filename in the ^+++ line.
Removed files must have /dev/null as filename in the ^--- line.
patch(1) will recognize this and either refuse to append to an existing file,
or it will unlink and deleted file.

Currently the ^--- and ^+++ lines will just contain the filename for both.
Looking through the 1.3 sources, there is appearently no support for handling add/deletes.
