This patch does the following: - make Buffer::insertStringAsLines work when inserting in nested insets
- set autoBreakRows_ to true for the top-level inset. Alfredo, is that right? - fix a first crash in BufferView::Pimpl::MenuInsertLyXFile The situation of inserting files in nested insets is however very bad, since Buffer::readDocument can only use a pit_type as argument and this argument is actually never used :( Indeed, readDocument, which does the hard work, is never invoked. Would it be right to pass also a ParagraphList argument to Buffer::readFile and BufferReadDocument? Or is it better in this case (and in Buffer::insertStringAsLines) to pass a dociterator (or a cursor slice) to indicate where to insert. I ask, because buffer.C does not use cursors at all. Comments welcome. JMarc
