M-x shell-script-mode

type:
foo &&
bar

This will make the second line (bar) indented. While this may be desired
sometimes, in some cases it is not. I use && for control flow throughout
my whole program, which makes this indentation not useful.

A fix was offered here, which I use now:

Maybe this could be made a configurable option?

I've now added this to Emacs 29 under the name
`sh-indent-statement-after-and'.  If anybody has a better name, feel
free to adjust.
