+Bash-Release:	4.2
+Patch-ID:	bash42-013

+Bug-Reported-by:	Marten Wikstrom <marten.wikstrom@keystream.se>
+Bug-Reference-ID:	<BANLkTikKECAh94ZEX68iQvxYuPeEM_xoSQ@mail.gmail.com>

+
+Bug-Description:
+
+An off-by-one error caused the shell to skip over CTLNUL characters,
+which are used internally to mark quoted null strings.  The effect
+was to have stray 0x7f characters left after expanding words like
+""""""""aa.
