+	* generic/tclCompile.c (TclCompileScript): Reduce the frequency with
+	which we issue INST_START_CMD, making bytecode both more compact and
+	somewhat faster. The optimized case is where we would otherwise be
+	issuing a sequence of those instructions; in those cases, it is only
+	ever the first one encountered that could possibly trigger.
