doc: unify scdoc style

This unifies the style of the man page source files. Most noticable are
the now consistent line endings at 80 chars (assuming a tabwidth of 8).

 # WINDOW DIMENSIONS and POSITION
+
 Layout generators are not supposed to include padding or leave space for window
 borders. The window dimensions will be shrunk by river to make space for these.
 River enforces a minimal window width and height of 50.
 
 Layout generators operate on a special coordinate grid from 0 to the maximum
-useable width or height of an output with the coordinate 0-0 being positioned at
-the top-left corner of the useable area of an output. While layout generators
-are free to place windows everywhere (including coordinates below zero or above
-the maximum width or height of an output), beware that the relative positioning
-of this grid on the screen can not be expected to remain constant. River applies
-an offset to window positions, depending on outer padding and the presence of
-desktop widgets like bars. Layout generators can therefore not position windows
