Regarding the application of binary diffs: I thought that Charles knew
this, and that he was simply punting on applying binary diffs to
anything other than the exact source file to which they were meant to
be applied (as for text files, for which context is useable, those
diffs come from section 1 of the format, and are represented in
unidiff format not svndiff).
I didn't quite follow your point about applying tree modifications via
editor commands. True, we don't have any way of representing context
or handling fuzziness in tree rearrangements, but that's a Subversion
problem in general. The question is, would the proposed format
preclude the addition of features to handle fuzziness later? If it
would, what's a better format?
