do_test() currently uses strcmp() twice to determine which operator is present; once to determine how many arguments the operator needs, then a second time to actually decode the operator and implement it.
Rewrite the code so that a table lookup is used to translate the operator string to an integer, and use a more efficient switch statement to decode and execute the operator.
This approach also acts as enablement for the following patches.
This patch should introduce no behavioural change.

v3: New patch.
Wow that's some interesting code...it took me a while to understand both the old and the new code. It looks correct to me but I wonder if it is deserving of some tests? Something like test/command_ut.c might show a simple way to run some tests.
OK, I'll send V4 of this series with your minor issues addressed, and I'll send a separate follow-on series which adds the unit tests, just so it doesn't delay or cause revisions to the main series.
