The fact is that the regexp
	/branches/KDE/(\d.\d)/kdelibs/

Does not match a path changed in that change. The tool isn't smart enough to 
detect that destination path of the copy is a parent dir of a match (though I 
have a vague memory of it auto-recursing in some conditions). That's what the 
recurse action is for: it's to cause it to list the path and apply the rules 
again.

Yes. Note the $ at the end, to cause the regexp to stop matching, so that the 
rule only applies to when the branching we'd done was parsed.
