How to show data in hex format?

[R. Bernstein]

If gdb is the inferior debugger then one can use a gdb command and the
gdb way, e.g. p/x expression

Zarko Zivanov contributed a patch a while ago to make viewing on x68
nicer. It might have also had some hex patches. His patch has been
encorprated into the pydb branch of ddd and there was a test release a
while ago with this.
