Eli, those whitespace changes look a little suspicious to me, they
result in a docstring like this:

    Apply FUNCTION to each element of SEQUENCE, and concat the results as 
strings.
    In between each pair of results, stick in SEPARATOR.  Thus, " " as
      SEPARATOR results in spaces between the values returned by FUNCTION.
    SEQUENCE may be a list, a vector, a bool-vector, or a string.
    SEPARATOR must be a string.
    FUNCTION must be a function of one argument, and must return a value
      that is a sequence of characters: either a string, or a vector or
      list of numbers that are valid character codepoints.
