0.5.11.3: fyi: reverse solidus "expanded away"

[Steffen Nurpmeso <steffen@xxxxxxxxxx>]

Hello.

Just fyi, i stumbled upon this a minute ago:

  #?0|kent:steffen$ echo du \\\\\
  > hey
  du \\hey

That was bash 5.1.8.

  #?0|kent:steffen$ dash
  #kent:$ echo du \\\\\
  > das
  du \das
  #kent:$

This is dash 0.5.11.3 (compiled by gcc (CRUX-x86_64-multilib)
10.2.0 on 2020-12-26), running on CRUX-Linux via glibc 2.32/3.
Ciao,
