mdocml: Move check for closing punctuation into its own function.

[kristaps@mdocml.bsd.lv]

Log Message:
-----------
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.
