Re: Bash Manual section 6.7 Arrays should mention array append notation

[Zachary Santer]

I'm consulting the online manual
<https://www.gnu.org/software/bash/manual/html_node/index.html>, so if
you're looking for a version number, that would be 5.1.

I just now looked at doc/bash.pdf in the git repo on Savannah. No info on
appending is present under bash-5.2-testing or devel.

Regards.
Zack
