Title: Fix filemode comparison in diffs

File modes were both not being ignored properly on platforms where they should be ignored, nor be diffed consistently on platforms where they are supported.

This change adds a number of diff and status filemode change tests. This also makes sure that filemode-only changes are included in the diff output when they occur and that filemode changes are ignored successfully when `core.filemode` is false.

There is no code that automatically toggles `core.filemode` based on the capabilities of the current platform, so the user still needs to be careful in their `.git/config` file.
