Bug#409179: DASH: Settings IFS=$'n' doesn't work properly

Package: dash
Version: 0.5.3-6

I ran into a problem after upgrading my system to testing last week,
causing one of my scripts not to work anymore. During installation I let
the installer redirect sh to dash. Although it is POSIX compliant (as
far as I know) it doesn't work properly. This was caused by the fact the
dash doesn't understand that setting IFS=$'\n' means that the seperator
is EOL. Instead dash just sees it as IFS='n' . I think it's a bug,
although not sure...

Hi, a IFS=$'\n' syntax isn't specified in POSIX, you should set it this
way:

$ IFS='
'
$
