Hello! I'm used to "svn cp" within the same WC, everything seems to work fine. I just read this warning and now I wonder if this is relevant for my use case.
svn help cp [...] WARNING: For compatibility with previous versions of Subversion, copies performed using two working copy paths (WC -> WC) will not contact the repository. As such, they may not, by default, be able to propagate merge tracking information from the source of the copy to the destination. Thanks! Paul
