Log Message:
-----------
Explicitly state that the cases in the inner switch in term_fill()
are exhaustive.  While there is no bug, being explicit has no downside
is is potentially safer for the future.

Michal Nowak <mnowak at startmail dot com> reported that gcc 4.4.4
and 7.4.0 on illumos throw -Wuninitialized false positives.
