editor: do not reread all data upon branching
Branch creation is a special case of add_directory(). Until now, it was
handled by enumerating branch parent files and creating svncopy records
which were later converted into open files or pushed into the
RevisionData. By default, there is no reason to record anything, the
files are the same than in the parent changeset. The tricky part is to
correctly check the source is the parent revision. This change massively
speeds up regular branching operations.
