Enclose file paths in double quotes to capture spaces

[paulbalandan]

Description
The pre-commit hook fails parsing files when the file paths contained spaces. My solution is to enclose the file path $PROJECT/$FILE in double quotes. This solution works with PHP's built-in linter. For Code Sniffer, I can't make it read the enclosed file path as a single file. It still breaks them at the spaces. Perhaps a bug in Code Sniffer? I don't know.

As a workaround, I only passed the relative file paths of the files to phpcbf. Tested locally, and phpcbf can still check the files.
