Re: diff --summarize [was: svn commit: r1159880 ...]

Hi Neels.

The new diff --summarize code presently still downloads the full text of
each deleted file to supply to the diff callbacks. I have a patch in
progress (attached) to eliminate this, but I shan't be working on it for
a few days. With this patch, 'diff --summarize' still works but I
haven't checked carefully (either by testing or analysis) that this is
actually eliminating all the unnecessary downloads, and it could do with
some documentation updates in the diff callbacks to say that this usage
is allowed.

Feel free to progress this if you wish, otherwise I'll get back to it
later.
