* Add a single prefix parser macro word to execute a host command, e.g.

  h: px

  such that these don't need to be duplicated in the namespace.

* add some support for byte streams.  this probably needs a 2-byte
  "execute" or a 1-byte indirection, or say a table of file

Maybe some more general indirection handling should be in order, also
for "pulled in" code.  1-byte indirection is handy, since it's the
data unit.
