patch

(from Werner Almesberger)

This patch fixes the "mdump" and "medit" shell commands:

- "mdump" got the length argument wrong and would only produce useful
  output if it was omitted.

- "medit" overran the argument list, choking on the NULL pointer
  following the last argument.

Note that "medit" still only does byte-sized accesses, which limits
its usefulness on most systems.
