# 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 through the commit filter alone, then
# with the flag off globally and off for the one repository. The repository
# carries a mailmap, so the idents are checked to follow it. Commits with no
# block, or nothing but one, are checked as well.
