* regex.c (re_compile_pattern): '\0111' should be '\011' plus '1',

  since octal literals are formed by three digits at most.

* eval.c (rb_eval_cmd): cbase should not be NULL; it should be
  either ruby_wrapper or Object.

* enum.c (enum_each_with_index): should return self.

* process.c (proc_setpgrp): should return value for non-void function.

* process.c (proc_getpgid): should raise exception if getpgid() return -1.

* string.c (rb_str_ljust): should return a duplicated string.

* string.c (rb_str_rjust): ditto.

* string.c (rb_str_center): ditto.
