[BUG] dash uses $* instead of $@ in variable assignments

[Gioele Barabucci <gioele@xxxxxxxxx>]

Hello,

I am forwarding a bug [1] reported by a Debian user: dash incorrectly
uses `$*` instead of the requested `$@` inside variable assignments.
The current version of dash is affected by this bug.

A simple test from the original reporter:

    $ dash -c 'IFS=:$IFS ; set -- a b c ; echo "$@" ; x="$@" ; echo "$x"'
    a b c
    a:b:c

    $ bash --posix -c 'IFS=:$IFS ; set -- a b c ; echo "$@" ; x="$@" ;
echo "$x"'
    a b c
    a b c

This error is reproducible with dash 0.5.7 and with the current master
git master branch, commit 2e5842258bd5b252ffdaa630db09c9a19a9717ca.
