That's correct. Subversion is putting supurfluous mergeinfo on
individual files. It is a known issue. If you do a lot of
refactoring (like I do) then eventually the svn:mergeinfo property
will wind up on every single file in the repository and as a result
every merge will touch those files regardless of whether not their
contents changed. I also believe it will cause some strange results
in the show log dialog box. Note, that this is not a TortoiseSVN
problem, but a problem with Subversion itself.

What I have been doing to work around the problem is to remove the
unneeded svn:mergeinfo properties before I do a commit. If you follow
the best practice of only merging at the root then only root should
ever have the svn:mergeinfo property. That will make things easier.
You can then create an empty svn:mergeinfo property all children of
the root (hopefully there aren't too many at that level) and then
recursively delete the ones you created. That will wipe out all
instances of the property below the root. That will preserve
mergeinfo only on the root where it is really needed.

I'm actually a little surprised that this hasn't received a lot of
attention. Aside from cluttering the log it will prevent you from
doing a reintegrate merge.
