Use different seperator for application directories

[timonbimon]

Hi again :)

Is it possible to use a seperator other than ':' for the application directories.
The colon does not seem to play well with the .pre-commit-config.yaml

For the following .-pre-commit-config.yaml

repos:
-   repo: https://github.com/asottile/reorder_python_imports
    rev: v1.3.4
    hooks:
    - id: reorder-python-imports
      args: [--application-directories=.:src]
      language_version: python3.7

I get the following error:

An error has occurred: InvalidConfigError: 
==> File /Users/timon/code/luminovo/project/.pre-commit-config.yaml

You should quote the string, see for example pytest's config
