    string.c: shrink too big buffer

    * string.c (rb_str_resize): shrink the buffer even if new length

is same but it is enough smaller than the capacity.
* file.c (expand_path): shrink expanded path which no longer needs
rooms to append. [ruby-core:63114] [Bug #9934]

    * string.c (rb_str_resize): should consider the capacity instead
      of the old length, as pointed out by nagachika.

    * string.c (rb_str_resize): update capa only when buffer get
      reallocated.
