Symptoms:
	PHCO_28467:
	Repackaged HP-UX patch PHCO_27565 for VVOS

	Based on HP-UX patch PHCO_27565:
	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 not set to C.

	3.sort '-o' option loops infinitely, and a line
	  repeats itself forever as an output only in certain
	  situations for multibyte locales.

	4.sort(1) fails to remove duplicates with -u option for the
	  non C locales.

	PHCO_19404:
	Repackaged HP-UX patch PHCO_17809 for VVOS

	Based on HP-UX patch PHCO_17809:
	sort -k1 option fails for ascii characters
	whose value is > 127.

	Based on HP-UX patch PHCO_13587:
	UTF8 changes incorporated for various options for sort

Defect Description:
	PHCO_28467:
	Repackaged HP-UX patch PHCO_27565 for VVOS

	Based on HP-UX patch PHCO_27565:
	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 occured 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 internal 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 occured only
	  in case of multibyte locales.

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

	4.sort(1) fails to remove duplicates with -u option
	  as the code was not copying the full record to the
	  save area for non C locales. The partial copy was a
	  resulting as non C locales can have '\n' as a key.

	Resolution:
	 The code has been modified to take care of the above
	 problem by handling the swapping of records appropriately.

	PHCO_19404:
	Repackaged HP-UX patch PHCO_17809 for VVOS

	Based on HP-UX patch PHCO_17809:
	sort -k1 option was failing for ascii characters
	with values > 127 due to improper typecasting of
	the pointer variable holding the characters to be
	sorted.

	Resolution:
	The pointer variable holding data to be sorted has
	been typecasted to unsigned character to facilitate
	correct sorting of ascii characters > 127.

	Based on HP-UX patch PHCO_13587:
	Enhanced the sort option -i for UTF8 locale changes

Enhancement:
	No
