Looking at the section title here:
https://www.postgresql.org/docs/devel/typeconv-union-case.html
..there is a 0.5em margin-left and margin-right on the words marked up with
<literal> tags, which in turn adds enough whitespace to make it look a
whitespace error (a space before the comma). Is there a case where we need
this margin or can it be tweaked to make titles like this one look better.
