    doc/meref.me.in: Fix content and style nits.
    
    * Annotate display vertical spacing `\n(dv` as a percentage.
    * Stop saying footnote and delayed text is "automatically"; the
      mechanism is spelled out; nothing more should be implied.
    * Take notice of the fact that footnotes might contain something other
      than text.
    * Use active voice more.
    * Wrap `sz` presentation and its preceding section heading in a keep
      because we've bought so much space on the previous page.  Temporarily
      set `bs` register to zero to make the keep invisible.
    * Tighten description of `sz` macro considerably.
    * Try to clarify usage of `TH`.
    * Suppress sentence-ending detection after a Latin abbreviation.
    * Drop spurious word.
