/**
 * Prepends a padding string to every line of the input text.
 *
 * Splits on `\n`, prepends `padding` to each line, and rejoins with `\n`.
 * Because empty strings and trailing newlines also split into lines, the
 * padding is applied there too — see the examples.
 *
 * @param text - The text to indent. Lines are delimited by `\n`.
 * @param padding - String prepended to each line. Defaults to two spaces.
 * @returns The indented text.
 *
 * @example
 * ```typescript
 * stringIndent('foo\nbar');          // '  foo\n  bar'
 * stringIndent('foo\nbar', '\t');    // '\tfoo\n\tbar'
 * ```
