Subject: bug#17735: add ability to spell-check only new changes in a diff

From: Glenn Morris <[email-masked]>

Package: emacs
Version: 24.4
Severity: wishlist

I'd like support for checking spelling in diff-mode, only checking the
spelling of the new version of the parts that changed.
So I can more easily find typos I'm about to add. :)
