"There"?  There is no suitable place to put such a link, other than my
new node.  Such a strategy would unbalance "The Outside Context" by
having most of its contents in subsubsections, and the bit about point
corruption at the other end of a link, in some random page.

As a matter of interest, one of the other nodes under "The Outside
Context", namely "Checking Whether to Stop" has just 13 lines.

We should describe it in the PRIMARY relevant place.

It is only tangentially related to edebug-save-windows.  It is about
point getting corrupted.  An angry victim of this bug should be be able
to find the description by searching for "corrupt".

Yes, stuff about options belongs in the "Options" page.  Stuff about
point getting corrupted does not, except at the other end of a link.
