svn copy WC-WC and empty mergeinfo

With RC7 on Windows when locally copying a file with

   svn cp file1 file2

an empty svn:mergeinfo property is added to file2. Is this (still)
necessary and correct? Initially this behavior has been introduced with
r26495, when --use-merge-history still existed.

 From my current understanding it does no harm when keeping implicit
mergeinfo for a copied file (it's the same as for added files, where
svn:mergeinfo isn't emptied, too!?) It should be even correct to keep
explicit as well as implicit mergeinfo: When merging to the copied file
from a source which had already been merged to its copy source, the
merge shouldn't be performed again. But this would happen with an empty
mergeinfo.

Of course, these cumulations of empty mergeinfos are also not very
aesthetic :)
