prompt: We are currently solving the following issue within our repository. Here is the issue text:
  --- BEGIN ISSUE ---
  System hooks with spaces in entry are not runnable
  It's pretty reasonable to have a system hook that looks like this:
  
  ```
  -   id: foo
      name: foo
      entry: python -m bar
      language: system
  ```
  
  Currently this fails:
  
  ```
  $ pre-commit run foo --all-files
  foo...................................................Failed
  
  xargs: python -m bar: No such file or directory
  ```
