Over time, ripgrep has grown its own tty detection code which includes a hack for (seemingly reliably) detecting the presence of a tty on Windows inside mintty. Would you be interested in a PR that brings it to this crate?

There isn't much code, but you can see it all here: https://github.com/BurntSushi/ripgrep/blob/master/src/atty.rs

There is a pretty long issue on the topic of mintty detection here, which includes the provenance of the hack: BurntSushi/ripgrep#94 --- Spoiler alert: it's what git does.
