warning, predict.mboost() with offset

[sbrockhaus]

This is just a comment about a warning.
The warning occurs when predicting a model with newdata, where the model is specified with an offset AND length(offset) != 1, then one gets
warning("Offset not used for prediction when ", sQuote("newdata"), " is specified")
(mboost.R, line 269)

I found the warning rather misleading, as only the combination of user-specified offset of length>1 and predict with newdata is a problem (and not the newdata in general)
warning("User-specified offset in object is longer than 1, thus offset not used for prediction when ", sQuote("newdata"), " is specified")

That sounds like a very reasonable change. Thanks
