* generic/tclCmdMZ.c (Tcl_SwitchObjCmd): [Bug 3106532]: Corrected
resulting indexes from -indexvar option to be usable with [string range]; this was always the intention (and is consistent with [regexp -indices] too). ***POTENTIAL INCOMPATIBILITY*** Uses of [switch -regexp -indexvar] that previously compensated for the wrong offsets (by subtracting 1 from the end indices) now do not need to do so as the value is correct.
