Subject: [PATCH] man: use <varname> and <option> instead of <literal> in
 systemd.link(5)

This looks better and allows those terms to be indexed in systemd.directives.
In particular, <literal></literal> is dropped from around section names
([Match] and others) because the parens are distinctive enough on their own.
The same style is used in systemd.unit(5) and other pages that describe
sections.
