glibc uses 'restrict' in getgrent_r(), fgetgrent_r().
Let's use it here too.

.../glibc$ grep_glibc_prototype getgrent_r
grp/grp.h:131:
extern int getgrent_r (struct group *__restrict __resultbuf,
		       char *__restrict __buffer, size_t __buflen,
		       struct group **__restrict __result);
.../glibc$ grep_glibc_prototype fgetgrent_r
grp/grp.h:161:
extern int fgetgrent_r (FILE *__restrict __stream,
			struct group *__restrict __resultbuf,
			char *__restrict __buffer, size_t __buflen,
			struct group **__restrict __result);
.../glibc$
