Fixed the misplaced $FreeBSD$.

Mention the new bind(1) sh builtin.

One external utility was ommitted in the previous delta:

Remove the printf builtin command from sh(1), which command is not
used so often that it's worth keeping it as a builtin.

Now that all the printf invocations from within the system startup
scripts, we can safely remove it.

No MFC is planned so far because it may break compatibility and
violate POLA.

I don't drop the printf builtin while I'm here because some /etc/rc.*
scripts seem to use it before mounting /usr where printf(1) resides.

Remove the bogusly inserted ``cwd'' which isn't a builtin command

Fix the header line of the table to use cross-references and
emphasis.

I didn't expect this to be merged to STABLE. It was, so correct the
HISTORY section.

Add missing entry for read(1) to the builtin(1) manual page and
add an MLINKS entry for it. I can't imagine how I missed this one.

Improve shell documentation:

* Consistently misspell built-in as builtin.

* Add a builtin(1) manpage and create builtin(1) MLINKS for all shell
builtin commands for which no standalone utility exists. These MLINKS
replace those that were created for csh(1).

* Add appropriate xrefs for builtin(1) to the csh(1) and sh(1) manpages,
as well as to the manpages of standalone utilities which are supported
as shell builtin commands in at least one of the shells. In such
manpages, explain that similar functionality may be provided as a
shell builtin command.

* Improve sh(1)'s description of the cd builtin command. Csh(1) already
describes it adequately. Replace the cd(1) manpage with a builtin(1)
MLINKS link.

* Clean up some mdoc problems: use Xr instead of literal "foo(n)"; use
Ic instead of Xr for shell builtin commands.

* Undo English contractions.
