From code inspection the math in handle_ctrl_cmd() looks super sketchy because it subjects -1 from cmdptr and then does a "% KDB_CMD_HISTORY_COUNT". It turns out that this code works because "cmdptr" is unsigned and KDB_CMD_HISTORY_COUNT is a nice power of 2. Let's make this a little less sketchy. This patch should be a no-op.
