    tmac/mdoc/doc-common (Dt): Fix code style nits.
    
    * Use idiomatic indentation.
    * Drop excess close-brace escape sequences.
    * Stop putting multiple close-brace escape sequences on one input line;
      reserve that idiom for special cases like the C switch/case emulation
      documented in our Texinfo manual.  One instance here _does_ use that
      model, but since it has only 3 cases it doesn't need multiple closing
      braces.  (ie/el covers two cases and requires 0 brace pairs.  Three
      cases require ie/el/if and one brace pair.  A "default" case would
      require a final `el` but that situation is not handled here.)
