Fixes denoland#6831 The dedent function was using `.trimEnd()` which removes ALL trailing whitespace including multiple newlines. This is inconsistent with npm:string-dedent which only removes a single trailing newline. Changes: - Replace `.trimEnd()` with `.replace(/\n[\t ]*$/, "")` to only strip a single trailing newline (with any preceding whitespace on that line) - Updated documentation to reflect the new behavior Before: ```ts dedent\` a \` // returns 'a' (all trailing newlines stripped) ``` After: ```ts dedent\` a \` // returns 'a\n' (only one trailing newline stripped) ```
