Sheldon Hearn 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.

.Sh NAME
.Nm pwd
.Nd return working directory name
.Sh SYNOPSIS
.Nm pwd
.Sh DESCRIPTION
.Nm Pwd
writes the absolute pathname of the current working directory to
the standard output.
.Pp
Some shells may provide a builtin
.Nm
command which is similar or identical to this utility. Consult
the
.Xr builtin 1
manual page.
.Sh DIAGNOSTICS
The
.Nm
utility exits 0 on success, and >0 if an error occurs.
.Sh STANDARDS
The
.Nm
utility is expected to be
.St -p1003.2
compatible.
.Sh SEE ALSO
.Xr builtin 1 ,
.Xr cd 1 ,
.Xr csh 1 ,
.Xr getcwd 3 ,
.Xr sh 1
.Sh BUGS
In
.Xr csh 1
the command
.Ic dirs
is always faster because it is built into that shell. However,
it can give a different answer in the rare case
that the current directory or a containing directory was moved after
the shell descended into it.
