Description of issue

The recipe for llm is causing
-bash: complete: nosort: invalid option name
for new shells.

I don't see "nosort" in https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/l/llm.rb so I imagine this could be a bug elsewhere in homebrew.

but the generated file
/opt/homebrew/Cellar/llm/0.28/etc/bash_completion.d/llm
clearly has this bash function

_llm_completion_setup() {
    complete -o nosort -F _llm_completion llm
}

Trace:
+++ . /opt/homebrew/etc/bash_completion.d/llm
++++ _llm_completion_setup
++++ complete -o nosort -F _llm_completion llm
-bash: complete: nosort: invalid option name

It's a months-old upstream issue when using the stock macOS bash.

This is more from enabling Click Bash completions in Homebrew:

• Should :click shell completions be enabled for Bash? brew#20188

Ideally users wouldn't use the ancient system Bash, which Apple is unlikely to ever update as Bash 4+ is under GPL-3.0-or-later. Apple doesn't distribute software under that license and is trying to get rid of GPL stuff wherever possible.

But we could consider moving the completions to the modern Bash completions directory , share/bash-completion/completions, which will only be picked up when bash-completions@2 is installed (or manually configured by user). This is a better directory as allows lazy loading completions, improving shell startup performance.

EDIT: The following PR will change the default directory. It will require rebuilding formulae to change path
