Symptoms:
	PHCO_24160:
	1. "patch -p0 < <filename>" dumps core on some
	    but not all files.

	PHCO_20818:
	   When a diff file of zero lines of context is
	   applied to a file, patch(1) dumps core with
	   an "Assertion failed" error. When the reverse
	   diff of zero lines of context is applied to a
	   file, patch command reports "Unexpected end
	   of hunk" error.

Defect Description:
	PHCO_24160:
	1."patch -P0 < <file name>" core dumps on some but not
	   all files even after applying PHCO_20818. One can
	   reproduce the problem like the following:

	$ cat css
	line1
	line2
	line3
	line4
	line5
	line6
	line7
	line8
	line9

	$ cat r2.patch
	Index: css
	diff -c css:1.25.2.1 css:1.25.2.2
	***************
	*** 1,7 ****
	  line1
	  line2
	  line3
	! line4
	  line5
	  line6
	  line7

	+ newline16

	
	$ ../patch -p0 < r2.patch
	Hmm...  Looks like a new-style context diff to me...
	The text leading up to this was:
	--------------------------
	|Index: css
	|diff -c css:1.25.2.1 css:1.25.2.2
	--------------------------
	Patching file css using Plan A...
	Hunk #1 succeeded at 5.
	Assertion failed: fillsrc==p_end+1 ||
	fillsrc==repl_beginning, file
	pch.c, line 719
	Abort(coredump)

	Resolution:
	The core dump was due to context diff file Parsing.
	This problem is rectified and the modified
	Patch(1) is thoroughly tested.

	PHCO_20818:
	   The diff file of zero lines of context is not
	   interpreted correctly because of the missing
	   conditions. The previous related defect fix
	   did not consider this case.

	   Resolution:
	   More conditions are added to make sure that the
	   diff file of zero lines of context is interpreted
	   correctly and patching is done appropriately.
