You mean something like

#ifdef FOPEN_OPENS_DIRECTORIES
inline static FILE *fopen_compat(const char *path, const char *mode)
{
       struct stat st_buf;
       if (stat(path, &st_buf) || !S_ISREG(st_buf.st_mode))
               return NULL;
       return (fopen(path, mode));
}
#define fopen fopen_compat
#endif

in git-compat-util.h, right?

Yeah, I can see that, even if I think the overhead would not be _that_ 
crucial.  But it is a nice way of fixing _all_ fopen() calls at the same 
time.
