Symptoms:
	PHCO_28515:
	1. Repackaging of 10.20 patch PHCO_27564 to 10.26 (TOS)

	(PHCO_27564:)
	1. Improper handling of certain files by sort(1).
	2. When sorting by field, sort(1) skips the last character
	   if a file does not terminate with a newline character and
	   LANG is set to a locale other than C.
	3. sort '-o' option loops infinitely, and a line repeats
	   itself forever as an output only in certain situations
	   for multibyte locales.

	(PHCO_19559:)
	1. sort(1) gives an error "... more than 20480
	   characters" on ja_JP.SJIS locale.
	2. sort -u fails to remove duplicates in non-C locales
	3. sort(1) misbehaves for huge data intermittently

	(PHCO_17799:)
	1. sort -k1 option fails for ascii characters whose value
	   is > 127.

	(PHCO_15833:)
	1. sort(1) reports errors while sorting binary data.
	   sort(1) will not support binary data after 10.20.

	(PHCO_13500:)
	1. UTF8 changes incorporated for various options for sort

	(PHCO_10589:)
	1. sort(1) behaves incorrectly when the field_end for a sort
	   key is not specified

	(PHCO_8768:)
	1. Customer   uses   command   "sort  -t  "|" <filename>" on
	   HP-UX  10.01. He gets an error  message:  "A line of the
	   input file contains more than 20480 characters." This
	   error  does only occur if LANG is set to de_DE.iso88591,
	   with LANG="C" everything works fine.

Defect Description:
	PHCO_28515:
	1. Repackaging of 10.20 patch PHCO_27564 to 10.26 (TOS)

	(PHCO_27564:)
	1. Improper handling of certain files by sort(1).

	Resolution:
	   The code has been modified to handle the files
	   appropriately.

	2. When sorting (by field) a file which does not have a
	   terminating newline, and where the LANG variable is not
	   set to C, the command does not output the last character
	   of the file. The problem occurred because the integer
	   counter was not being incremented to handle the new line
	   character.
	   Here are the steps to reproduce the problem:
	# echo 'one one\ntwo two\c' > TST
	# cat TST
	one one
	two two
	[ note that there is no newline at the end of file ]
	# unset LANG ## First, the correct results:
	# sort -k 1,1 TST
	sort: Warning: A newline character was added to the
	 end of file TST.
	one one
	two two
	# export LANG=french
	# sort -k 1,1 TST
	sort: Warning: A newline character was added to the
	 end of file TST.
	sort: Warning: A newline character was added to the
	 end of file TST.
	one one
	two tw <=== the "o" in "two" has been removed

	Resolution:
	   The problem was due to one of the variable (used to count
	   the number of newlines) not getting properly incremented
	   when the newline appears.
	   The problem was corrected by incrementing the counter to
	   handle the newline character appropriately.

	3. The sort(1) command  loops infinitely in certain cases,
	   and the problem was due the incorrect return value on
	   encountering WEOF.It was not returning a NULL at end of
	   file hence sort(1) went into an infinite loop as it was
	   not able to fine the end of file.This occurred only in
	   case of multibyte locales.

	Resolution:
	   The sort(1) code has been modified to return NULL on
	   encountering  EOF.
