From d44be71f515f8494313986bc8379bc35f75dc802 Mon Sep 17 00:00:00 2001
From: Kristaps Dzonsons <kristaps@bsd.lv>

Subject: Move check for closing punctuation into its own function.  This will
 later be modified to remove the need for iscdelim(), which will be used to
 unify delimiter checks, which will then allow for the simple removal of a
 TODO regarding escaped periods.
