When View/Nonprinting Characters is selected, space characters that fall around
an automatic line break are suppressed. This creates a user problem in the
detection of multiple spaces between words, where only one might be desired.

The spaces remain in the document, as evidenced by subsequent editing, therefore
it is anomalous to hide them from the creator/editor,especially as the user
might be a member of that highly desirable group, former Microsoft Word users,
where this behaviour does not occur.
