We could just see if the hunk applies to the unchanged index (still
assuming we're inside 'add -p'), and if not, reject the edit.

Unfortunately git-apply does not seem to have a --dry-run option.
(Even stranger, when given the option --dry-run it tries to open a
patch of that name.)  What is the recommended way to do such things?
Make a backup copy of the index and apply --cached anyway?
