Gerry, the immigration laws are confusing and subject to continual change, making it very difficult for most of us to keep up with what we are supposed to do (credit to the regular posters on this board who do so well) - however, I find this comment quite offensive.
If it is so obvious that the visa had expired, then why didn't you do something about it sooner?

I may be wrong, but I believe that there is a mistake and it's in your opinion (and Boulevard's) - not on the part of the ECO.

At first, you will be allowed to stay and work in the UK for
two years. Near the end of this time, if you are still married and intend to continue living together, you can apply to stay permanently in the UK.
Leave to Enter allows spouses to come and go from the UK but only for a fixed period of time - the visa that allows them to stay in the country is ILR - Indefinite Leave to Remain. This is what is issued following the application referred to above.
As to the present legal status of your wife in the UK - did the Immigration Officer stamp her passport? Hopefully he did, extending her right to stay in the UK.
