When the location of .git is several levels above the directory with Cargo.toml, bacon is started there and will not find anything to check and does not produce a result file.

Expected behavior
I would expect that the cwd before bacon is started, is to the configured root_pattern directory, which should be the one with Cargo.toml.

Attach bacon-ls.log
In this case .git resides in the castle-neovim folder.

bacon-ls.log
