doc/syntax.tex: Reformat the various grammar fragments.

  * Move the prose descriptions to the final case (e.g., for
    <string-literal-char> and <char-literal-char>).

  * Present alternatives on a single line where possible.

  * Use centre-level dots consistently to denote elisions of
    alternatives.

  * Space alternatives consistently.
