// SwUndoDelete has to perform a deletion and to record anything that is needed
// to restore the situation before the deletion. Unfortunately a part of the
// deletion will be done after calling this Ctor, this has to be kept in mind!
// In this Ctor only the complete paragraphs will be deleted, the joining of
// the first and last paragraph of the selection will be handled outside this
// function.
// Here are the main steps of the function:
// 1. Deletion/recording of content indices of the selection: footnotes, fly
// frames and bookmarks
// Step 1 could shift all nodes by deletion of footnotes => nNdDiff will be set.
// 2. If the paragraph where the selection ends, is the last content of a
// section so that this section becomes empty when the paragraphs will be
// joined we have to do some smart actions ;-) The paragraph will be moved
// outside the section and replaced by a dummy text node, the complete
// section will be deleted in step 3. The difference between replacement
// dummy and original is nReplacementDummy.
// 3. Moving complete selected nodes into the UndoArray. Before this happens the
// selection has to be extended if there are sections which would become
// empty otherwise. BTW: sections will be moved into the UndoArray if they
// are complete part of the selection. Sections starting or ending outside
// of the selection will not be removed from the DocNodeArray even they got
// a "dummy"-copy in the UndoArray.
// 4. We have to anticipate the joining of the two paragraphs if the start
// paragraph is inside a section and the end paragraph not. Then we have to
// move the paragraph into this section and to record this in nSectDiff.
