I _think_ that in this case the code will override the default update. I 
can confirm that DEPM works, for example.

To be fair, I did not remember that we had this information in 
LyXAction.cpp :)

What it does is change the default update flag before going through 
dispatch. I am not sure that this is written in the best (and safest) 
possible way, though.
