xargs: Before exiting, wait for all invocations of the utility.

This only has an effect with -P, otherwise errors are only detected when the
utility is not running.

Add a new -o option to tell xargs(1) to reopen /dev/tty as stdin in
the child process, before executing the command. This is very useful
when you do stuff like ``find ... | xargs interactive_application''.
Without -o, the application would inherit the pipe as its stdin, and
you thus lose any control over it.

This flag has been carefully chosen to not conflit with other options
of other xargs utilities like GNU xargs.

Extend our -R extension which sets the number of arguments in which -I will
replace to support magic values less than zero, which mean to just go nuts
and expand as many as we want.

mdoc(7) police: most -mdoc macros can take multiple arguments.

Add the -P option which executes multiple copies of the specified utility
in parallel. Idea from GNU xargs.

When giving an example that relies on shell expansion/globbing, don't use a
replstr for -J that will be interpereted by the shell.

Note that this appeared at least as early as PWB UNIX.

Use the literal string 'PWB UNIX', as we still have no .At macro for it.

Modify the -p implementation to use a user's locale, so they can respond to
the prompt in their native language.

Also make the prompt fit what POSIX asks for (?...).

This should not affect use of -p with yes(1) [as every locale I know of matches
'y' as YESEXPR as well], but that's what -t is for anyway. -p is meant to be
really used interactively.

Submitted by: tjr, jmallett

A markup fix, and document -R as non-standard.

Make -J a proper flag internal to the code (rather than just check for
use of replstr and lack of Iflag), and add -R, which when given with
-I controls the number of arguments on which replacement will be done.

Some people happen to think it's idiotic to limit to 5 arguments, so
let the user override it if they like.

After 3 months...

Merge xargs(1) with that of xMach.

Bring in xargs(1) changes to add -L and -I as per the Single Unix Specification
version 3. Proper exit status numbers are implemented, and the manual page has
been updated to reflect reality.

The code has been ANSIfied, and a new file has been added to xargs(1) to do the
substring substitution as SUSv3 requires.

Traditional behaviour should not be affected, use of -J should be deprecated
in favor of the more portable -I (though -J has been left, for now).

Submitted by: me, tjr (the exit status stuff)

Spelling police: extention -> extension.

Add a -J replstr option that allows the user to tell xargs to insert
the data read from standard input at a specific point in the command
line arguments rather than at the end.

Alphabetize command-line options in the synopsis.

mdoc(7) police: Fixed typo and markup in rev.1.11.

o The -s limit is ARG_MAX - 4K, not ARG_MAX - 2K.
o Mention that the current environment is part of the -s calculation.
o Add a BUGS section that warns against executing a program that increases
the size of the argument list or the size of the environment.

I have wondered for a while what the difference is between

get a big list | xargs sudo command

which fails and

get a big list | sudo xargs command

which succeeds. The answer is that in the first case, sudo expands
the environment and pushes the amount of data passed into execve over
the E2BIG threshold.

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.
