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

154 // 1. Deletion/recording of content indices of the selection: footnotes, fly
155 // frames and bookmarks
156 // Step 1 could shift all nodes by deletion of footnotes => nNdDiff will be set.

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