'svn diff' describes svn:mergeinfo property diffs as "Merged ..." or "Reverse merged..." rather than using the unified diff output style that it uses for other property values.
With Subversion 1.8.9: [[[ $ svn propget -rBASE svn:mergeinfo A; svn propget svn:mergeinfo A /trunk:10-15,20-25 /trunk:10-18,20-25 $ svn diff Index: A =================================================================== --- A (revision 1) +++ A (working copy) Property changes on: A ___________________________________________________________________ Modified: svn:mergeinfo Merged /trunk:r16-18 ]]] With Subversion trunk the last part of the output changes to: [[[ Modified: svn:mergeinfo ## -0,0 +0,1 ## Merged /trunk:r16-18 ]]] The line beginning with "##" has crept in, where it was previously omitted. I assume this is unintentional, as the information in it is not useful. - Julian
