* tests/trace.test: Extended array tracing tests.
* doc/trace.n: Clarified information about when array traces will
be fired.
* generic/tclVar.c (Tcl_ArrayObjCmd): Corrected call to CallTraces
(for TCL_TRACE_ARRAY) to only be called when the variable is
either an array or is undefined, to ensure that array traces do
not fire for scalar variables.
