Log Message:
	* generic/tclCompCmdsSZ.c (TclSubstCompile): If the first token does
	not result in a *guaranteed* push of a Tcl_Obj on the stack, we must
	push an empty object. Otherwise it is possible to get to a 'concat1'
	or 'done' without enough values on the stack, resulting in a crash.
	Thanks to Joe Mistachkin for identifying a script that could trigger
	this case.
