Support Ctrl+W to clear password field

[3v1n0]

Describe the feature you'd like see implemented in sudo-rs

Using Ctrl+W in the password field writes a new char

What problem can be solved with this feature?

You'd expect the field to be cleared, as it happens in UIs when using Ctrl+Backspace in a password field.

In this case we should not care about words, since it may reveal information about the typed password.

Are there examples of other software / password prompts where ^W clears the input line?

[Alxhr0]

Shells like Bash, Nushell and probably others support that

ctrl+w in shells removes a single word, not the entire line. We would like an example of other software where it clears the entire line.

I would also be interested in:

• Examples of a normal passwordpassphrase prompt (i.e. one with visual feedback) in which ^W clears a word, or
• Users who attest to this being something they rely on in older versions of ogsudo (cf. our criteria for inclusion: if something is a common use case we should consider it). In that case we should also recommend Todd to implement this in ogsudo, since he has also moved away from using the regular line discipline for passwordpassphrase input.

I think I'm leaning towards, if we implement ^W it should clear a word.

Note also, I am not concerned about "would it reveal something".
