tidy is not good at detecting untracked files

[robinmoussu]

When running x.py test, I got a bazillion errors (434 to be more precise). I think that all those errors comes from .js files. Most (all?) of them being:

missing trailing newline
line longer than 100 chars

Is this "expected"? Because of those errors, the command finishes with an error code (exit code: 1).

@robinmoussu that's from tidy - do you have untracked files maybe? tidy tries to avoid untracked files but it's not very good at it.

I was effectively that. I generated the doc for rustc_parse and rustc_lexer by running cargo doc directly in those folder. Even a cargo clean didn't clear the target directory, and I didn't noticed it.
