Hmm.  Given that we already have

#ifndef __GNUC__
#ifndef __attribute__
#define __attribute__(x)
#endif
#endif

in git-compat-util.h, it is really between:

    __attribute__((format (printf, 1, 2)))
    void advise(const char *advice, ...);

    __attribute__((format (printf,2,3)))
    extern void strbuf_addf(struct strbuf *sb, const char *fmt, ...);

and

    FORMATPRINTF(1,2)
    void advise(const char *advice, ...);

    FORMATPRINTF(2,3)
    extern void strbuf_addf(struct strbuf *sb, const char *fmt, ...);


Perhaps I am biased for staring at our source code for too long, but
somehow the latter looks unnecessarily loud, spelled in all caps.

I dunno.  What does this really buy us?
