always zeroed anyway.
cmd_help() is now able to print out help about the specified command
only - it will also print out all aliases of that command. Reduced
the distance between the command name and its description; NULL
descriptions are now also allowed.
There is now a find_command() function that's used throughout the
module. Like in the Be debugger, it will now also accept partial
matches, i.e. "co" will most probably match "continue" (as long as
there is no new "co*" command added by another component). It will
first try to find an exact match, and only if that failed it will
search for a partial match.
