152 // the first and last paragraph of the selection will be handled outside this

155 // 1. Deletion/recording of content indices of the selection: footnotes, fly
156 // frames and bookmarks

159 // section so that this section becomes empty when the paragraphs will be
160 // joined we have to do some smart actions ;-) The paragraph will be moved
161 // outside the section and replaced by a dummy text node, the complete
162 // section will be deleted in step 3. The difference between replacement
163 // dummy and original is nReplacementDummy.
164 // 3. Moving complete selected nodes into the UndoArray. Before this happens the
165 // selection has to be extended if there are sections which would become
166 // empty otherwise. BTW: sections will be moved into the UndoArray if they
167 // are complete part of the selection. Sections starting or ending outside
168 // of the selection will not be removed from the DocNodeArray even they got
169 // a "dummy"-copy in the UndoArray.
170 // 4. We have to anticipate the joining of the two paragraphs if the start
171 // paragraph is inside a section and the end paragraph not. Then we have to
172 // move the paragraph into this section and to record this in nSectDiff.
