/// Repeats content to fill a line.
///
/// This can be useful when implementing a custom index, reference, or outline.
///
/// Space may be inserted between the instances of the body parameter, so be
/// sure to include negative space if you need the instances to overlap.
///
/// ## Example
/// ```
/// Sign on the dotted line: #repeat[.]
///
/// #set text(10pt)
/// #v(8pt, weak: true)
/// #align(right)[
/// Berlin, the 22nd of December, 2022
/// ]
/// ```
///
/// ## Parameters
/// - body: Content (positional, required)
/// The content to repeat.
///
/// ## Category
/// layout
