+# The trailer table on the commit page. A commit whose message ends in a
+# trailer block is rendered with enable-trailers on, through the exec dump
+# filter as both trailer filter and email filter so the arguments each one
+# receives show in the page, then with the flag off globally and off for the
+# one repository. A commit with no block is checked to get no table.
