Thanks.  I'll keep living with the prompt and maybe eventually file an
enhancement bug to make it optional.

It shows my options for emerge.

$ emerge -ad firefox
myaction None
myopts {'--with-bdeps': 'y', '--load-average': 11.2, '--debug': True, '--jobs': 8, '--ask': True, '--ask-enter-invalid': True}
This action requires superuser access...
Would you like to add --pretend to options? [Yes/No] n

Since --ask-enter-invalid appeared in that bit of code, I tried taking
it out of my options in make.conf -- as I expected, that didn't
change whether I get the prompt, just changed how I can answer it.
