Subject: Check the trailer values each path takes

The ident said to follow the mailmap had no entry in it, and the
commit filter that takes a value when no trailer filter is set had no
test, nor did brackets without an address, a message of nothing but a
block and the repository flag turning the table on. One test appended
to the shared config, and seven read a page an earlier test fetched.
