I thought it would be helpful to try to give you a better example, so
I dusted off the old repository we used to use to test some of the
merge tracking scenarios. Refer to this graphic:


I have a working copy of trunk and I do the merge shown as r14 (which
is what will be created when I commit this merge). Here is the
command I run and the diff output of the mergeinfo:

$ svn merge ^/branches/b .
--- Merging r10 through r13 into '.':
A products/roadmap.html
U products/index.html
U about/index.html
U index.html
U news/index.html
 U .
--- Recording mergeinfo for merge of r10 through r13 into '.':
 G .

$ svn diff
Index: .
--- . (revision 13)
+++ . (working copy)

Property changes on: .
Modified: svn:mergeinfo
   Merged /branches/a:r6,8-11
   Merged /branches/b:r10-13

This gives a simple example to talk about. What changes would you
propose making to this output?
