  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.
