>Description:
	The xargs man page mentions a -I option at the top, but gives
	no further mention of it in the rest of the docs. This option
	is not implemented in the code. -I is documented, however, in
	SuS2, along with a number of other options we do not implement
	that we probably should to be standards conformant.
	See, for example:
	http://www.opengroup.org/onlinepubs/007908799/xcu/xargs.html
>How-To-Repeat:
	man xargs, vi the code, look at the web page above
>Fix:
	Probably someone should start with the Austin Group document
	and implement whatever it requires of xargs, then document it.

This is indeed a problem.

Responsible-Changed-Why:  
There is a posting by Masao Uebayashi on tech-userlevel dated August 16, 2001 
which implements -I and -i; it's still pending in pre-review state.  I'll 
have a look at it and will either integrate it or come up with something 
of my own if necessary.

State-Changed-Why:
We now seem to have everything besides -i, -l, and -e, which optionally take
an argument (thus breaking getopt) -- are they really worth it? I deduce from
the commit log that FreeBSD may not think so.

 If we want to claim to be standards conformant we probably have to
 implement the standard...

 What about -i, -l, and -e (see the PR)?

 These predate -I -L and -E (the POSIX versions) and are documented to
 be obsolete in the linux man page. Although our getopt supports optional
 arguments now, it is not worth it in my opinion to emulate obsolete behavior.

 This PR is another proof to my theorem: Wait long enough and every problem
 gets magically fixed.

 POSIX doesn't seem to indicate that they're obsolete. It lists them
 at any rate, and describes their functions without deprecating them.

 Heh, looking at the 1997 man page will give you such information!!! :-)
 Instead if you look the the "fresh" 2004 version:

 http://pubs.opengroup.org/onlinepubs/009604599/utilities/xargs.html

 You'll also see the rationale for their removal.

 You are indeed correct.

 All right, in that case this issue is definitely dead. (it's already
 closed, so it's staying that way.)
