-B/--bell flag

[shurizzle]

Despite the -B/--bell flag being considered "Doubtful" in issue #129, I believe it has great value.

For example, topgrade can take quite some time during updates, long enough for the session to expire. Once expired, if one doesn't notice, the task fails, and one might have to restart a compilation, which can sometimes be lengthy.

For this reason, I use the -B flag, so I don't have to constantly monitor a long batch process and can be alerted by a beep when needed.

I have already implemented this feature in my branch—if you agree, I could open a PR right away.

Thanks for opening the issue and creating a solution at the same time!

I note that both with ogsudo and sudo-rs you can also get a bell by putting a bell character in the --prompt (or even SUDO_PROMPT). Although that does feel a bit hacky perhaps.

I would invite to open the PR anyway (I've looked at your branch and it looks reasonable to me, but it's easier to discuss if we have the PR). In any case, you've already put in the work, so nothing to lose there.

Of course we take a strict stance around adding features, but I'm inclined to say this one will fit.

Edit Moved the --bell from "Doubtful" to "To be decided"

(I noted with interest that “—prompt” was also in Doubtful but we implemented that anyway.)
