1762 I have fixed BackSpace (and thus Delete) to not delete
1763 double-spaces automagically. I have also changed Cut,
1764 Copy and Paste to hopefully do some sensible things.
1765 There are still some small problems that can lead to
1766 double spaces stored in the document file or space at
1767 the beginning of paragraphs. This happens if you have
1768 the cursor between to spaces and then save. Or if you
1769 cut and paste and the selection have a space at the
1770 beginning and then save right after the paste. I am
1771 sure none of these are very hard to fix, but I will
1772 put out 1.1.4pre2 with FIX_DOUBLE_SPACE defined so
