+delete a sentence in auto fill

Basically adds the functionality necessary to delete sentences in auto
fill mode, where it may not be possible with simple vim motions and
where Emacs functions kill the paragraph.

+** Delete a sentence in auto fill
+In long lines via truncate lines, deleting till the end of the
+sentence was easy via vim motions. However, the same action is
+difficult with auto-fill-mode where sentences are separated through
+(potentially several) newlines which makes vim motions
+difficult. Thus, I propose some form of functionality which allows you
+to:
+
+- Find the next closest period denoting the end of the sentence
+- Delete the region between the point of invocation and the found period
+
+This essentially does the same task as vim motion based deletion, but
+can handle the newlines. To not trample on the toes of any package,
+I'll set it to "M-d" (kill-word), the most inoffensive binding
+possible which is still mnemonic.
+
+First, the function. I'll use search-forward (from zap* lib) to find
+the period. Then auto-fill to make it look nice.
