x binary #106469Description
Starting with #104552, ./x.py test tidy fails on my system:
thread '<unnamed>' panicked at 'called `Result::unwrap()` on an `Err` value: Error("unexpected character 'H' while parsing major version number")', src/tools/tidy/src/x_version.rs:36:58
I have an executable installed on my system called x that is unrelated to rust. I would prefer if tidy didn't execute it at all.
