Change interpreter from octets to hex?

[Joshua Datko]

Hello,

Is it possible to change the default interpreter behavior to display
hex instead of octets for bytevectors and u8-lists? And if so, how to
do so?

The default, as y'all know is:

scheme@(guile-user)> #vu8(#x0a #xaa)
$6 = #vu8(10 170)

But I would like instead the output to be:
$6 = #vu8(#x0a #xaa)

It's easy enough to make a format function but it'd be more convenient
if this was the default for me.

Thanks,

Josh
