svn backend returns different diff to git/hg backends
In vcsserver calling
a_vcs_backend.diff(rev1='same', rev2='same', path1='samefile', path2='samefile').raw_data
returns for SVN:
Index: samefile =================================================================== diff --git a/samefile b/samefile --- a/samefile\t(revision 2) +++ b/samefile\t(revision 2)
and empty string for both git / hg
Not sure what the correct thing to do is here, empty string makes sense but maybe not when a path has been given in?
