Both POSIX and glibc use 'restrict' in getline(), getdelim().
Let's use it here too.

.../glibc$ grep_glibc_prototype getline
libio/stdio.h:621:
extern __ssize_t getline (char **__restrict __lineptr,
                          size_t *__restrict __n,
                          FILE *__restrict __stream) __wur;
.../glibc$ grep_glibc_prototype getdelim
libio/stdio.h:611:
extern __ssize_t getdelim (char **__restrict __lineptr,
                           size_t *__restrict __n, int __delimiter,
                           FILE *__restrict __stream) __wur;
