BASH PATCH REPORT
=================
Bash-Release: 4.0
Patch-ID: bash40-013
Bug-Reported-by: jidanni@jidanni.org
Bug-Reference-ID:
Bug-Reference-URL: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=519165
Bug-Description:
Though references to $@ when there are no positional parameters will now
cause the shell to exit if the `errexit' option has been enabled, constructs
such as ${@:-foo} should not cause an exit.
Patch:
