    grn(1): Fix English style nits.
    
    * Hyphenate stranded prefix in compound expression.
    * Uncapitalize independent clause after colon (and don't precede it with
      an empty request).
    * Don't introduce lists with a sentence fragment.
    * Hyphenate "floating-point" (number(s)).
    * Use indefinite articles where warranted.
    * Heighten register: from "chopped" to "truncated".
    * Add comma to separate elements of a complex conjunction.
    * Use more idiomatic English.
