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.
