    ghc-pkg: don't expand ${name}-style env vars by default · 6ef41c26

    For shell-based build systems the feature is still available as:
      ghc-pkg register --expand-env-vars
    
    Historically, ghc-pkg allowed environment variables to appear in the
    input files for ghc-pkg register. They are not stored in the package
    database but are expanded upon registration. This feature helped for
    build systems based on makefiles and shell scripts. These days the
    vast majority of such files are generated by Cabal and we don't want
    any ${name} strings (e.g. perhaps in a package description) getting
    accidentally interpreted as an environment variable.
