 `committer`, and `tagger`) can be suffixed with `name`, `email`,
 and `date` to extract the named component.
 
-The complete message in a commit and tag object is `contents`.
-Its first line is `contents:subject`, where subject is the concatenation
-of all lines of the commit message up to the first blank line.  The next
-line is `contents:body`, where body is all of the lines after the first
-blank line.  The optional GPG signature is `contents:signature`.  The
-first `N` lines of the message is obtained using `contents:lines=N`.
+The complete message of a commit or tag object is `contents`. This
+field can also be used in the following ways:
+
+contents:subject::
+	The "subject" of the commit or tag message.  It's actually the
+	concatenation of all lines of the commit message up to the
+	first blank line.
+
+contents:body::
+	The "body" of the commit or tag message.  It's made of the
+	lines after the first blank line.
+
+contents:signature::
+	The optional GPG signature.
+
+contents:lines=N::
+	The first `N` lines of the message.
+
 Additionally, the trailers as interpreted by linkgit:git-interpret-trailers[1]
 are obtained as `trailers` (or by using the historical alias
 `contents:trailers`).  Non-trailer lines from the trailer block can be omitted
