The "attribute((format))" safety seems to bite us here...

    $ Meta/Make --pedantic builtin/commit.o
        CC builtin/commit.o
    cc1: warnings being treated as errors
    builtin/commit.c: In function 'prepare_to_commit':
    builtin/commit.c:741: error: zero-length printf format string

In wt-status.c many similar ones exist, unfortunately.
