10 | | Having a closed way, removing one of the inner (i.e. not the first/last) node leaves the way closed - OK. Removing first/last node opens the way. |

11 | | A 3-nodes closed way, removing the inner node, creates self-overlapping way with 2 nodes and 2 segments. |

12 | | Two ways sharing one node, selecting the node and short way. Removes the node from longer, not selected way. |

13 | | Selecting node(s) //and// its(their) way. Removes the node(s) from the way - OK. Selecting any number of extra ways that don't touch the node(s) - does the same and ignores the extra selected ways. |
