the search mode and current radix are mapped to __local__ Q-Registers ^X and ^R now (refs #17)
* This way the search mode and radix are local to the current macro frame,
unless the macro was invoked with :Mq.
If colon-modified, you can reproduce the same effect by calling
[.^X 0^X ... ].^X
* The radix register is cached in the Q-Reg table as an optimization.
This could be done with the other "special" registers as well, but at the
cost of larger stack frames.
* In order to allow constructs like [.^X typed with upcarets,
the Q-Register specification syntax has been extended:
^c is the corresponding control code instead of the register "^".
