As recently discussed here,
http://svn.haxx.se/dev/archive-2012-06/0078.shtml
URL->[WC|URL] copies and moves still will make the copy source's inherited
mergeinfo explicit on the destination (assuming the source has *no* explicit
mergeinfo of course[1]). When copying between branches this makes sense, since
valid merge history may be lost otherwise. There are cases however where it
doesn't add any information and instead only adds "noise" in the form of
needless new explicit mergeinfo properties:
1) The source's inherited mergeinfo is empty
2) The source and destination inherit mergeinfo from the same parent
3) Other cases???
While the current behavior doesn't cause any harm re the correctness of
mergetracking, it is potentially a bit confusing. Ideally inherited mergeinfo
would not be propagated in these cases.
[1] If a copy source has explicit mergeinfo, that mergeinfo is always copied to
the destination, we are talking here only about cases where the source has *no*
explicit mergeinfo.
