Patch-ID:	bash42-036

Bug-Reported-by:	gregrwm <backuppc-users@whitleymott.net>
Bug-Reference-ID:	<CAD+dB9B4JG+qUwZBQUwiQmVt0j6NDn=DDTxr9R+nkA8DL4KLJA@mail.gmail.com>
Bug-Reference-URL:	http://lists.gnu.org/archive/html/bug-bash/2012-05/msg00108.html

Bug-Description:

Bash-4.2 produces incorrect word splitting results when expanding
double-quoted $@ in the same string as and adjacent to other variable
expansions.  The $@ should be split, the other expansions should not.

Patch (apply with `patch -p0'):
