mysqlslap: specifying --engine and --create does not work with --engine=<storage_engine>:<option>

[Hakan Küçükyılmaz]

How to repeat:

1) <option> is missing and does not work with replication
mysqlslap \
  --delimiter=";" \
  --create="CREATE TABLE A (a int);INSERT INTO A Values (23)" \
  --query="SELECT * FROM A" \
  --concurrency=1 \
  --iterations=1 \
  --engine=memory:max_rows=200 \
  -vvvvv \
  --post-system="echo SHOW CREATE TABLE A | mysql -uroot mysqlslap"

...
set storage_engine=`memory`;
CREATE TABLE A (a int);
