Don't create hard links for files that are not important

[zkochan]

Currently, all the files of a package are hard linked into. However, there are some files that are not used by code, they can be skipped during hard linking:

• markdown files: README.md, CHANGELOG.md, HISTORY.md, CONTRIBUTING.md
• all files in the test/, tests/, example/, examples/ folders
• CI config files: .travis.yml, .appveyor.yml
• editor configs: .editorconfig
• npm/yarn stuff: .npmrc, .npmignore, npm-shrinkwrap.yaml, yarn.lock
• git things:.gitignore, .gitattributes, .github/
• LICENSE, LICENCE

Edit:

This features looks similar to yarn autoclean

Hi @zkochan, any updates on this? How about just having pnpm autoclean which would do the same as yarn autoclean?
Additionally, it could be cool to have some parameter to pnpm install which would prevent those files being linked in the first place. This could be default on CI env

P.S.
As a temporary solution, for anyone looking at this, there is https://github.com/tj/node-prune
