At least when regtool is used interactively, it is IMO not very useful 
to have
modem-line-noise-like output for REG_BINARY, but human readable output for
the other value types.
But this is the current behavior of "regtool get ...".


Suggest to combine the best of both worlds:

regtool get KEY\\VALUE

should always produce human readable output, in particular a hex dump
for REG_BINARY.
(But this would change existing behavior on REG_BINARY)


regtool -b get KEY\\VALUE

writes REG_BINARY as binary data to stdout.


regtool -b set KEY\\VALUE 01 02 03

sets REG_BINARY value from hex bytes in args.


regtool -b set KEY\\VALUE -

set value from binary data read from stdin
