?format does describe the return value, though in the Details section 
rather than in Value:

      These functions convert their first argument to a vector (or
      array) of character strings which have a common format (as is done
      by 'print'), fulfilling 'length(format*(x, *)) == length(x)'.  The
      trimming with 'trim = TRUE' is useful when the strings are to be
      used for plot 'axis' annotation.

I'll try to make it clearer.
