rust-config: fix incorrect coercion of null values to false...
rust-config: fix incorrect coercion of null values to false As explained in the previous changeset: Probably being too trigger happy about boolean values, I incorrectly set the transform for a `None` to a `Some(false)`. It would cause for example the `ui.formatted` value to be set to `Some(false)`, which turns off the colors among other things, when `None` would trigger the automatic behavior.

/// Keeps information on whether plain mode is active.

/// Plain mode means that all configuration variables which affect

/// ignored. Additionally, the output should be stable,
/// reproducible and suitable for use in scripts or applications.
///
/// The only way to trigger plain mode is by setting either the
/// `HGPLAIN' or `HGPLAINEXCEPT' environment variables.
///
/// The return value can either be
/// - False if HGPLAIN is not set, or feature is in HGPLAINEXCEPT
/// - False if feature is disabled by default and not included in HGPLAIN
/// - True otherwise
