Use of backticks in description breaks build

[srid]

When description contains backticks:

{
  description = "Foo `bar` qux";
}

we see:

error: builder for '/nix/store/bhr9lfplzh0352yh4n6gnxdbjqbba7wh--.drv' failed with exit code 1;

Another related issue is that using single-quotes will also break the build:
description = "refresh machine's cargo-cabal from Cargo.toml";

Produces a , script of:

showHelp () {
  echo -e "Available commands:\n"
  echo -e '## Dev Tools';echo;echo '  , cargo-cabal	: cargo-cabal
  , dev	: Start watchexec
  , docs	: Start Hoogle server for project dependencies
  , fmt	: Format the source tree
  , refresh-machines	: refresh machine's cargo-cabal from Cargo.toml
  , repl	: Start the cabal repl' | /nix/store/5yc1cplwszlddqj17989jshws1j14dl1-column-util-linux-2.38.1/bin/column -t -s ''$'	';
}

which includes the un-escaped '
