    Not adding a definition to a preexisting macro, what you did, but
    modifying the string registers documented in "Headers and footers"
    in groff_ms(7).

I can find no escape to change the format of a number register, such as
\n[%].  If the even footer is defined as:

    .EF '%'\\*[bookTitle]''

what escape may I insert before the % that is equivalent to ".af % i"
and does not cause groff to emit warnings at .bp's?
