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,

This is expected as dash's echo always processes backslashes. bash will 
give the same output when its xpg_echo option is enabled.
