The "Command-Line Interface" part of the documentation of timeit says:
python -m timeit [-n N] [-r N] [-u U] [-s S] [-h] [statement ...]
But actually the command can take additional two options, -p and -v, as the next part of the documentation describe.
So, for consistency, I suggest adding them into the usage part.
I've created the PR in case the issue is correct.
