Well, you would not know if the user gave you '-g' before you
ask setup_revisions() to parse the options, and once you let it
do its thing, you would not know if it also found an explicit
output format given by the end user, so your cannot sanely make
default depend on '-g'.

I suspect that it would have to be either somewhat involved or
outright hacky.
