Request: Support for new POSIX 2022 sh features #1050

The upcoming POSIX 2022 (lol) standard will include new features for many programs, such as set -o pipefail for sh.

Will the mvdan/sh AST need to be extended to add support for new flags?

set is just a builtin, so it's not represented in any special way in the syntax tree.

As far as I can see, this new POSIX standard version isn't finished yet. Until it is, I don't think we want to prematurely make any changes. I can't even find a link to the latest version of its shell language specification after ten minutes of looking around.
