Test that requires copying .git

[xd009642]

So I'm in a definitely very unique situation where I have a test that requires the repos .git folder so I need something a bit more aggressive than the --gitignore true flag. I'm currently using --in-place in a separate clone of the project to avoid accidentally breaking something so there is an easy way round this if this is too exotic

For the interested this is because I interact with the coveralls API and part of that API you provide some git and github metadata so I test against the repos own metadata to make sure I'm filling out the API fields correctly

Actually, despite working around that cargo-mutants doesn't run on tarpaulin... Dose cargo-mutants make use of unix signals if so that might break things for me 🤔

The easiest workaround for the git issue is probably `--in-place`, or copying it yourself then using that. The main thing cargo-mutants uses signals for is to kill hung tests, and to stop them if it's interrupted itself. Can you describe how to reproduce the problem with Tarpaulin?

So tarpaulin tests instrument binaries with breakpoints and do coverage which involves intercepting signals going to the process and handling them in code. There's a possibility I'm intercepting the cargo mutants kill signal and then failing the test because it's got an unexpected termination signal 🤔

Reproducing is pretty simple, it's just cloning tarpaulin and running cargo mutants on it

git clone --depth 1 https://github.com/xd009642/tarpaulin
cd tarpaulin
cargo mutants --in-place
