Fix the following whitespace formatting issues:
- Indentation in scdoc source files should be done with tabs.
- Lines where there (clearly) should be a line break, need to have '++'
at the end, but several were missing them.
- The scdoc manual (clearly) states that lines should be hard wrapped
at 80 columns, but when line(s) are indented, that causes rendering
issues. So lines where a line break was not clearly intended or
clearly not intended, have been put onto 1 line to circumvent the
rendering issue.
