* 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.
