Right. Maybe better to say it now matches the other implementation (dash
has two implementations and they were behaving differently).
I am unaware of another dash implementation. Do you mean ash from which
dash was forked? I have checked
https://en.wikipedia.org/wiki/Debian_Almquist_shell and noticed that
busybox ash implementation was derived from dash, but the similar issue
is still open in their tracker.
I would recommend users to check scripts by the "shellcheck" static
analyzer, but I am unsure if such suggestion is suitable for release
notes or for Debian news in the dash package.
