Zero-dimensional feature files work OK now.

("work" here means that the error is safely trapped.)

 ** more safety
 
-A couple of areas are not yet safe against runtime faults.  The simple
-case is zero-length features, which will lead to division by zero
-errors; more pressingly, large databases might well end up writing off

+    dbH->numFiles, maybe others), so that if something goes wrong in
+    the meantime the database is not in an inconsistent state.
