* generic/tclCmdMZ.c (Tcl_SwitchObjCmd): Generate
an error if a mode argument like -exact is passed
more than once to the switch command. The previous
implementation silently accepted invalid switch
invocations like [switch -exact -glob $str ...].
* tests/for.test: Check some error cases when
invoking continue and break inside a for loop
next script.
* tests/switch.test: Add checks for shortened
version of a mode argument like -exact. Add
test for more than one mode argument. Add test
for odd case of passing a variable as a
body script.
