man: Fix several whitespace formatting issues

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.
