illumos gate

"Mohamed A. Khalfella" <khalfella@gmail.com> gave me review feedback that I accepted, but then failed to include in the final deliverable (I think largely because of the very large time delay between the review and the integration).

Specifically, the deltas recommended but omitted are here:

--- a/usr/src/cmd/xargs/xargs.c
+++ b/usr/src/cmd/xargs/xargs.c
@ -129,7 +129,7 @ static char *mav; / modified argv, after parsing
static int n_inserts; /* # of insertions. */

/* our usage message:                                                  */
-#define        USAGEMSG "Usage: xargs: [-t] [-p] [-e[eofstr]] [-E eofstr] "\\
+#define        USAGEMSG "Usage: xargs: [-t] [-p] [-0] [-e[eofstr]] [-E eofstr] 
        "[-I replstr] [-i[replstr]] [-L #] [-l[#]] [-n # [-x]] [-s size] "\\
        "[cmd [args ...]]\\n"

@ -1020,6 +1020,7 @ process_special:
case 'p' :
case 't' :
case 'x' :
+ case '0' :
break;

case '-' :

These need to be included.
