If I understand you right you want to alter the interface of
PyFile_FromFile and PyFile_FromFileEx from

PyFile_FromFileEx(FILE *fp, char *name, char *mode, int (*close)(FILE*),
int buffering, char *encoding, char *newline)

to

PyFile_FromFileEx(int fd, char *name, char *mode, int (*close)(FILE*),
int buffering, char *encoding, char *newline)

?

I could write a patch and remove int (*close)(FILE*), too. It's no
longer used by the functions.
