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 between 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)
