I guess you are not using glimpse (which indeed has some restrictions on 
its use).  The code for calculating the grep tokens in the case of 
-use_glimpse is more clever, and indeed includes of_device (glimpse only 
works on individual words, but grep could include the struct as well).

I don't think there is any particular reason for the grep version to be 
different form the glimpse one, so I will try to fix it.
