Reduce complexity when parsing content

[ccoVeille]

The complexity of the code was increased with #13 by the multiple branching if

The parsing of the content could be moved out the main with something like this

contentStr, err := parseContent(flag)
if err != nil {
fmt.Println
os.Exitt(1)
}

// …

func parseContent(flag) string, error {
   if directText != {
      return *directText
   }

   // …
}
