Thinking about this more, this is pretty ugly. I'd prefer it if
aug_insert actually calls make_path and then passes that to tree_insert,
which sets the path to the newly created node before returning, so that
tree_insert ahs the signature

        int tree_insert(struct tree **tree, struct path *path, const char *label,
                        int before)

You have aug_cp working ? Excellent .. looking forward to the patch ;)

tree_create already sets a struct path up, so only tree_set needs to be
modified; since that is also used from builtin.c, it's probably easiest
to split the current tree_set into a tree_set (same signature as curent
version) and a tree_set_path with signature

        struct tree *tree_set_path(struct tree *root, struct path *path, const char *value)
        
that is called from aug_set.
        
I'd also split all that cruft I had for aug_insert into a static utility
function, something like 'aug_set_last_created(struct augeas *aug,
struct path *path)'
