Thinking about the behaviour of 'svn blame -r 50:20 file@50': Right now, if I'm not mistaken, it wants 'file@5 -r 20' to exist. Johan suggested it should automatically round 20 up to the oldest revision in which the file existed, to enable, for example, 'svn blame -r 50:0' by analogy to 'svn log -r 0:50'.
But what if the file existed in revision 10, got deleted in revision 11, and resurrected (by 'svn cp file@10 file && svn ci') in r30? What should the end of the blame chain be --- file@r30, file@r20, or file@r10? Daniel
