  91 // larger userbase with differenct access patters triggers the bad
  92 // behaviour. (segfaults.) What I think happen is: In several places
  93 // we store the paragraph in the current cursor and then moves the
  94 // cursor. This movement of the cursor will delete paragraph at the
  95 // old position if it is now empty. This will make the temporary
  96 // pointer to the old cursor paragraph invalid and dangerous to use.
  97 // And is some cases this will trigger a segfault. I have marked some
  98 // of the cases where this happens with a warning, but I am sure there
  99 // are others in this file and in text2.C. There is also a note in
 100 // Delete() that you should read. In Delete I store the paragraph->id
 101 // instead of a pointer to the paragraph. I am pretty sure this faulty
 102 // use of temporary pointers to paragraphs that might have gotten
 103 // invalidated (through a cursor movement) before they are used, are
 104 // the cause of the strange crashes we get reported often.
 105 //
 106 // It is very tiresom to change this code, especially when it is as
 107 // hard to read as it is. Help to fix all the cases where this is done
