描述

I love it when bat wraps lines in a single page of output. When output needs to be sent to the pager, though, the wrapped lines are actively unhelpful. I'm very used to issuing -S to less once a log file is open to change the line wrapping live.

I'd like a --wrap mode that behaves like auto for unpaged output, but never when piping to less.

研究方向
Start by examining the existing ` wrap` flag implementation in `src/bin/bat/clap app.rs` and the wrapping logic in `src/printer.rs`. The discussion in issue comments hints at how `less` is invoked with the ` S` flag; look at how paging is set up in `src/bin/bat/paging.rs`. The request is to add a new wrap mode that defaults to auto for direct terminal output but never wraps when paging. Consider adding a new variant to the `Wrap` enum and adjusting the paging setup to pass the correct ` no wrap` flag to `less`.
