- Adds quotes around all strings inserted into config files, preventing them from being interpreted as constants.
- Changed all private methods in OctoberEnv.php to protected.
- Updated test to check some config files for expected changes.
This fix will apply quotes around string environment variables which contain either a single, or double, quote as well as any variables with a hash symbol - escaping any double-quotes encountered. When artisan october:env is run, this should correctly transfer all configuration values from the config files to the .env file.
Fixes#4979.
