 So roughly speaking, if a unary operator (such as OP_COS) generates a
 warning, then following the direct child of the op may yield an
-OP_PADSV or OP_GV that gives the name of the undefined variable. On the
+OP_PADSV or OP_GV that gives the name of the undefined variable.  On the
 other hand, with OP_ADD there are two branches to follow, so we only print
 the variable name if we get an exact match.
