paste -d\\: avoid heap overrun for backslash at end of delim list
* src/paste.c: Include "quotearg.h".
(collapse_escapes): Handle backslash-escaped backslash explicitly.
Handle unescaped backslash at end of string by returning nonzero,
rather than by overrunning memory.
(main): Diagnose an invalid delimiter list -- carefully.
Reported by Cristian Cadar, Daniel Dunbar and Dawson Engler.
* tests/misc/paste-no-nl (delim-bs): Add a test to demonstrate the
heap-smashing capability.
(delim-bs2): Prior to coreutils-5.1.2, this bug was a little harder
to demonstrate: it would corrupt a first-argument containing e.g., \b
* NEWS: Mention the bug fix.
* tests/misc/Makefile.am (TESTS): Reflect renaming.
* tests/misc/paste: Rename from paste-no-nl.
