+A question arises: if the M206 offset is set, should this adjustment
+to the home position shift or change the possible range of movement
+permitted by the software endstops ?
+
+I have taken the view that the software endstops are a backstop safety
+feature which is not necessarily entirely accurate, and that reducing
+the scope of movement is not desirable.
+
+I have therefore implemented it so that negative values for M206
+increase the total range of movement, whereas positive values leave it
+unchanged.
+
+So for example with
+  #define X_MIN_POS 0
+  #define X_HOME_POS 0
+  #define X_MAX_POS 100
