Symptoms:
	PHCO_25918:
	( SR:8606259335 CR:JAGae23653 )
	Improper handling of certain files by sort(1).

	( SR:8606215245 CR:JAGad84433 )
	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.

	( SR:8606225452 CR:JAGad94539 )
	sort '-o' option loops infinitely, and a line
	repeats itself forever as an output only in certain
	situations for multibyte locales.

	( SR:8606202868 CR:JAGad72042 )
	Improper handling of certain files by sort(1).

Defect Description:
	PHCO_25918:
	( SR:8606259335 CR:JAGae23653 )
	Improper handling of certain files by sort(1).

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

	( SR:8606215245 CR:JAGad84433 )
	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.

	( SR:8606225452 CR:JAGad94539 )
	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 find 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.

	( SR:8606202868 CR:JAGad72042 )
	Improper handling of certain files by sort(1).

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