code: def _construct_values_list(values):
          
          lines = values.splitlines()
          values_list = lines[:1]
          values_list.extend(filter(None, lines[1:]))
          return values_list
docs: This values_list is a strange construction, because of ini format.
          We need to extract the values with the following supported format:
  
              >>> key = value0
              ...     value1
              ...
              ...     # comment line here
              ...     value2
  
          given that normally, either value0 is supplied, or (value1, value2),
          but still allowing for all three at once.
  
          Furthermore, with the configparser, we will get a list of values,
          and intermediate blank lines, but no comments. This means that we can't
          merely use the count of values' items to heuristically "skip ahead" lines,
          because we still have to manually parse through this.
  
          Therefore, we construct the values_list in the following fashion:
              1. Keep the first value (in the example, this is `value0`)
              2. For all other values, ignore blank lines.
          Then, we can parse through, and look for values only.
