[SVN] r3782

[Chris Thomas]

Refactoring:
• everything related to command line invocation is now in a CommitWindowController category.
• status string highlighting is now implemented as an NSString category.

Same code, different locations. No user-visible changes, so I'm not bothering to upgrade the binary.
