Some svn client command know how to follow moves, other don't.

I think the asf repo shows exactly those mistakes which svn drives its users into (and which I've made also, on a much smaller scale, of course). As far as I understand, the synapse repo there is historical, and they need to convert to git in order to feed it into a CMS. I don't know if OP is still interested. Michael
