What if you want to redirect the hex dump to a file? IMO, isatty() checks
are only useful if the output won't change qualitatively on redirection
(e.g., for coloring). Otherwise, it's always better to use an explicit
flag.
That said, attempting to "regtool get" a binary value is no different from
attempting to cat a binary file -- and we're not changing "cat" to output
hex dumps. What would be useful instead is a way to query the type of a
value via regtool. We could also add a "-h" (for --human-readable) flag
to always output the value in human-readable form (see below).
FWIW, 'A=`regtool get KEY1\\VAL`; regtool set KEY2\\VAL "$A"' will already
break for REG_MULTI_SZ type values. It would be good to make regtool's
behavior consistent: "regtool set -f FILE" reads the value from FILE,
which would work for all value types.
