Breaking up self-intersecting Polys at segments crossing
can't be done for the second segment.

Divide:
A new node is inserted and made start and end node.
For the second segment no division occurs or can be made.
Expected is that the segment the nearest to the selecting point is addressed.
Eg. the trim command.

Breakout gap:
- 1 Part fully trimmend of
- Can be undone

Auto trim:
(hint: do file-save first to revert)
- 1 Part fully trimmend of
- Undo will wipe the complete poly

In the file example 1.

Work-arround:
- Divide
- Insert node on the second segment not at the crossing
- Divide at that node
- Move new nodes to crossing

Please post one report per problem. I'm unable to identify how many problems this report is about.

I've fixed the problem I was able to reproduce here and changed the title accordingly.

I will try this in a new release so I can see what method was addressed.
Re-entered the first more elaborated because I didn't mentioned undo there.
