Another attempt at fixing the space removal issue. This method

Another attempt at fixing the space removal issue.  This method
combines the long-standing previous method (the one that removed spaces
between words correctly, at a cost of a leading extra space for the first
FOText instance of an fo:block) with my later patch (which would
fix the extra space issue but had problems with spaces between words).  It
appears to work well, but the fo:inline issues Simon brought up will still
need further work.
