  - Fix phpcbf exit code for lint-staged
    
    phpcbf exits with a failure exit code if there were any violations, even
    if they could all be fixed. This makes it useless in a lint-staged
    pipeline (which expects scripts to exit successfully, and will otherwise
    discard all changes and abort the commit), so wrap phpcbf in a small
    shell script checking the exit code and ignoring a 1 exit code. (Exit
    code 2 would mean that there were some errors that could not be fixed.)
    
    We can hopefully revert this when PHP_CodeSniffer version 4 is released,
    which is supposed to change the exit codes to make them more sensible
    (squizlabs/PHP_CodeSniffer#2898).
