URL-only renames adds svn:mergeinfo property

Hi,

I've just found (another) issue with using URL-only renames. If one of the
parent directories has svn:mergeinfo recorded on it, then renaming a file
via a URL results in the new file containing a full copy of what was on the
trunk (but cut down to the individual file).

Please see the following output from my test script (using SVN 1.6.13):

>svn merge file:///D:/temp/svn_sandpit/repository/trunk .
--- Merging r4 through r5 into '.':
U A\alpha.txt

>svn commit . --message "Merge r5 from trunk to branch."
Sending .
Sending A\alpha.txt
Transmitting file data .
Committed revision 6.

>svn propget svn:mergeinfo
file:///D:/temp/svn_sandpit/repository/branches/branchA
/trunk:4-5

>svn propget svn:mergeinfo
file:///D:/temp/svn_sandpit/repository/branches/branchA/A/alpha.txt

>svn rename
file:///D:/temp/svn_sandpit/repository/branches/branchA/A/alpha.txt
file:///D:/temp/svn_sandpit/repository/branches/branchA/A/beta.txt --message
"Rename alpha.txt to beta.txt on branchA."
Committed revision 7.

>svn propget svn:mergeinfo
file:///D:/temp/svn_sandpit/repository/branches/branchA/A/beta.txt
/trunk/A/alpha.txt:4-5

Notice that the 'svn propget' on alpha.txt indicates that there is no
svn:mergeinfo property available, but it gets added to beta.txt during the
rename.

Is this intended behavior?
