diff --no-index: clarify operation when not inside a repository
Clarify documentation for "diff --no-index". State that when not
inside a repository, --no-index is implied and two arguments are
mandatory.
Clarify error message from diff-no-index to inform user that CWD is
not inside a repository and thus two arguments are mandatory.
