Incorrect initial execution time in Nushell

[lewis-yeung]

The initial execution time in Nushell is always 823ms because of this code. I asked the maintainer of Nushell, and he said it was an "Easter egg" (see here). Unfortunately, let-env CMD_DURATION_MS = "0" does not work. However, a workaround can resolve it:

let-env PROMPT_COMMAND = {
    let cmd_duration = if $env.CMD_DURATION_MS == "0823" { 0 } else { $env.CMD_DURATION_MS }
    let width = (term size -c | get columns | into string)
    ^::OMP:: print primary $"--config=($env.POSH_THEME)" --shell=nu $"--shell-version=($env.NU_VERSION)" $"--execution-time=($cmd_duration)" $"--error=($env.LAST_EXIT_CODE)" $"--terminal-width=($width)"
}

@JanDeDobbeleer Should we do this?

@lewis-yeung what in the fresh hell? I suppose we indeed have to work around it. But I'd properly comment that code 😅
