Clarify GIT_DIFF_INCLUDE_UNTRACKED_CONTENT option

Browse Source 
This improves the docs for GIT_DIFF_INCLUDE_UNTRACKED_CONTENT as
well as the other flags related to UNTRACKED items in diff, plus
it makes that flag now automatically turn on
GIT_DIFF_INCLUDE_UNTRACKED which seems like a reasonable dwim type
of change.
