Follow-up to engraving punctuation

Browse Source 
Skip the terminal period only if there is true punctuation at the end of
the engraving, not degraded text.  This feels a bit janky because the
way engravings are malloced and structured uses this manual offset to
access the space allocated for text.  I used a macro to unify all those
accesses so that it will be harder to screw it up if something changes
in that respect, since repeating (ep + 1) as a magic number across
engrave.c seems quite brittle.
