Subject: * array.c (rb_values_at): extract common procedure from  
 rb_ary_values_at.  follow DRY principle.

* re.c (match_values_at): values_at should understand ranges.

* struct.c (rb_struct_values_at): ditto.

* struct.c (inspect_struct): inspect format changed; add "struct "
  at the top.

* sprintf.c (rb_f_sprintf): "%p" specifier for inspect output.
  (RCR#68)

* eval.c (rb_mod_undef_method): allow "undef_method" to accept
  multiple arguments. (RCR#146)

* lib/timeout.rb: put timeout in Timeout module. (RCR#121)
  [ruby-talk:61028]

* re.c (match_groups): new method added. (RCR#139)

* variable.c (rb_mod_const_of): should exclude constant defined
  in Object, unless retrieving constants of Object.

* string.c (rb_str_new4): do not allocate new string if original
  is frozen or already have copy-on-write entry. [ruby-talk:74940]
