Handling nested clones properly while scanning the text of the external file is more tricky than I imagined.
The immediate difficulty is deciding whether to clear v.children or not. In some cases we want to do that, in other cases not. The corresponding problem, when scanning the descendants of a cloned node, is whether to update v.parents and parent_v.children. The existing (horrible) code, solves this problem somehow, probably using yet another stack, and possibly by marking nodes as being visited. Presumably some valid way exists in the fast-read branch, but I'm not sure what it is. Edward -- You received this message because you are subscribed to the Google Groups "leo-editor" group.
