bug about svn diff --summarize

[李猛超]

Hello:


    If I have a file at version 1. then I modefy and commit it, get version 2, 
Now I make the file be same as version 1 and commit, get version 3.
    Running "svn diff -r 1", I will get no changes, but "svn diff -r 1 
--summarize" will get the file is modefied.


Best wishes,
