narrowed down on addressing the escaping of hyphens
in the dynamic creation of manuals whilst avoiding
them in creating help texts.  This lead to a sequence
of slipping through hyphens adrressed by additional
patches in aforementioned commit series.

On the other hand, postprocessing dynamically man-generator
created and statically provided manuals catches all hyphens
in need of escaping.

Changes:
- revert the above commits whilst keeping man-generator
  streamlining and the detection of any '\' when generating
  help texts in order to avoid escapes to slip in

- Dynamically escape hyphens in manaual pages using sed(1)
  in the respective Makefile targets

- remove any manually added escaping on hyphens from any
  static manual sources or headers
