arguments passed to 'puts' is always a newline.

io.c: recycle garbage on write
* string.c (STR_IS_SHARED_M): new flag to mark shared mulitple times
(STR_SET_SHARED): set STR_IS_SHARED_M
(rb_str_tmp_frozen_acquire, rb_str_tmp_frozen_release): new functions
(str_new_frozen): set/unset STR_IS_SHARED_M as appropriate
* internal.h: declare new functions
* io.c (fwrite_arg, fwrite_do, fwrite_end): new
(io_fwrite): use new functions
Introduce rb_str_tmp_frozen_acquire and rb_str_tmp_frozen_release
to manage a hidden, frozen string. Reuse one bit of the embed
length for shared strings as STR_IS_SHARED_M to indicate a string
has been shared multiple times. In the common case, the string
is only shared once so the object slot can be reclaimed immediately.

string.c (rb_str_tmp_frozen_release): release embedded strings
Handle the embedded case first, since we may have an embedded
duplicate and non-embedded original string.
* string.c (rb_str_tmp_frozen_release): handled embedded strings
* test/ruby/test_io.rb (test_write_no_garbage): new test
[ruby-core:78898] [Bug #13085]
io.c (rb_io_syswrite): avoid leaving garbage after write
As with IO#write, IO#syswrite also generates garbage which can
be harmful in hand-coded read-write loops.
* io.c (swrite_arg, swrite_do, swrite_end): new
(rb_io_syswrite): use new functions to cleanup garbage

io.c: remove rb_ensure usage for rb_str_tmp_frozen_* calls
Using rb_ensure pessimizes the common case and makes the code
more difficult to read and follow. If we hit an exceptions
during write, just let the GC handle cleanup as the exception
is already bad for garbage.
* io.c (io_fwrite): call rb_str_tmp_frozen{acquire,release} directly
(rb_io_syswrite): ditto
(fwrite_do, fwrite_end, swrite_do, swrite_end): remove

* io.c: [DOC] improve docs for IO

strings, it might include a perm or options hash argument;
IO.write has no length argument, drop corresponding statement),
improve formatting, call-seq, grammar.
* IO#sync=: remove unnecessary "produces no output".

This was made obsolete by r4190 back in July 2003. Furthermore,
this existed less than 3 months as it was only introduced in
r3782.
So with absolutely no references to rb_deferr, I doubt any vim
plugin would care anymore.

As it is just a hint the kernel is free to ignore,
IO#advise already succeeds when posix_fadvise is not
available build time at all. Following that, if posix_fadvise
was available at build time but not implemented in the running
kernel, we should also ignore it.
* io.c (do_io_advise): do not raise on ENOSYS
* test/ruby/test_io.rb (test_advise): do not skip on Errno::ENOSYS
