* generic/tclExecute.c: [Bug 3057639]. Applied patch by Jeff to
* generic/tclVar.c: make the behaviour of lappend in bytecompiled * tests/append.test: mode consistent with direct-eval and 'append' * tests/appendComp.test: generally. Added tests (append*-9.*) showing the difference. FossilOrigin-Name: 405a405dc7b5e6d2cf699bce59de6867a313fa6f
