I have fixed BackSpace (and thus Delete) to not delete

Copy and Paste to hopefully do some sensible things.

There are still some small problems that can lead to

double spaces stored in the document file or space at

the beginning of paragraphs. This happens if you have

the cursor betwenn to spaces and then save. Or if you

cut and paste and the selection have a space at the

beginning and then save right after the paste. I am

sure none of these are very hard to fix, but I will
|

put out 1.1.4pre2 with FIX_DOUBLE_SPACE defined so
|

that I can get some feedback. (Lgb)
