f9bcf9cabf Mark functions as __dead2 in order to help the LLVM static checker
understand which code paths aren't possible.

This commit eliminates 117 false positive bug reports of the form
"allocate memory; error out if pointer is NULL; use pointer".

91b7d6dc58 - Check and report write(2) errors.
- Issue a single writev(2) call instead of multiple write(2)s.
  This change improves the inefficiencies introduced when echo
  went on an stdio diet.

The following figures are for echoing 1000 arguments.
original stdio-based echo:
        0.01 real         0.01 user         0.00 sys
before:
        0.05 real         0.00 user         0.04 sys
after:
        0.01 real         0.00 user         0.00 sys

88d5eb7147 Refer to 1003.1-2001 in the Standards section now that TC1 allows the
traditional BSD behaviour (-n option) and FreeBSD extensions (\c).

6188858ae1 clarify code:
add comments.
don't get the length of each arg passed, only the last one.
check against == or != NULL rather than using a pointer value as
truth test.

e6d3cf2648 Correct some hard sentence breaks. Only those surrounding the previous
commit and those which cause ugly nroff output have been fixed, since
the purpose of the style guideline which they contravene is to reduce
the sizes of deltas.

c644db6aa2 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.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

6cef43a78b Well, it would appear that the "ayes" have it (though by a slim margin).
Apply my \c changes to echo.  It should also be noted that this is:
A) going into 2.2, not 2.1
B) a functional no-op unless you actually use it!
