-// This is the comments that some of the warnings below refers to.
-// There are some issues in this file and I don't think they are
-// really related to the FIX_DOUBLE_SPACE patch. I'd rather think that
-// this is a problem that has been here almost from day one and that a
-// larger userbase with differenct access patters triggers the bad
-// behaviour. (segfaults.) What I think happen is: In several places
-// we store the paragraph in the current cursor and then moves the
-// cursor. This movement of the cursor will delete paragraph at the
-// old position if it is now empty. This will make the temporary
-// pointer to the old cursor paragraph invalid and dangerous to use.
-// And is some cases this will trigger a segfault. I have marked some
-// of the cases where this happens with a warning, but I am sure there
-// are others in this file and in text2.C. There is also a note in
-// Delete() that you should read. In Delete I store the paragraph->id
-// instead of a pointer to the paragraph. I am pretty sure this faulty
-// use of temporary pointers to paragraphs that might have gotten
-// invalidated (through a cursor movement) before they are used, are
-// the cause of the strange crashes we get reported often.
-//
-// It is very tiresom to change this code, especially when it is as
-// hard to read as it is. Help to fix all the cases where this is done
-// would be greately appreciated.
