`cabal-rpm builddep && cabal install || stack install` panics

I tried mdsh on the following [readme.md](https://raw.githubusercontent.com/juhp/koji-tool/ae90d0371f15e754b4e397ffb38bbe68db280369/README.md): ``` Using input=File("./README.md") output=File("./README.md") work_dir=Parent(".") clean=false frozen=false `$ koji-tool --version` `$ koji-tool --help` `$ koji-tool builds --help` `$ koji-tool tasks --help` `$ koji-tool install --help` `$ koji-tool find` ` cabal-rpm builddep && cabal install || stack install` thread 'main' panicked at /var/home/petersen/.cargo/registry/src/index.crates.io-6f17d22bba15001f/mdsh-0.7.0/src/main.rs:387:25: WTF, not supported note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace ``` https://github.com/zimbatm/mdsh/blob/e9b0c3dd99b752bfb6a344935cc4e47424d453e7/src/main.rs#L387 Is there an easy way to ignore some backquotes?
