    groff_char(7): Fix content and style nits.
    
    Content:
    * Depict ASCII/ISO 8859/Unicode U+007C with \[or] instead of "|",
      because it looks better when typeset.
    * Illustrate appearance of \[bb] in contrast to \[or].
    
    Style:
    * Use commas correctly.
    * Recast for clarity.
    * Adjust dead-tree typography (fix orphaned words, adjust page breaks).
    * Tighten wording.
