* generic/tclBasic.c: Modified TclArgumentGet to reject pure lists

	* generic/tclCmdIL.c: immediately, without search. Reworked setup
	* generic/tclCompile.c: of eoFramePtr, doesn't need the line
	* tests/info.test: information, more sensible to have everything
	on line 1 when eval'ing a pure list. Updated the users of the line
	information to special case this based on the frame type (i.e.
	TCL_LOCATION_EVAL_LIST). Added a testcase demonstrating the new
	behaviour.
