# The trailer table on the commit page. A commit whose message ends in a
# trailer block is rendered with enable-commit-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. The repository carries a mailmap, so the sign-off idents
# are checked to follow it. A commit with no block is checked to get no table.
