A new whitespace "rule" is added that sets the tab width to use for whitespace checks and fix-ups and replaces the hard-coded constant 8. Since the setting is part of the rules, it can be set per file using .gitattributes. The new configuration is backwards compatible because older git versions simply ignore unknown whitespace rules.
