nit: errant movement of "*" here.

I'm assuming that you will be adding something that adds to extra_args
in a future commit. It might be better to just convert the "0" to "NULL"
here and add extra_args when you actually use it.

Creating a shorter variable name seems unnecessary.

This seems like a good opportunity to create and use a
strvec_concat() method.

Why is it the responsibility of this method to clear these args?
I suppose it is convenient. It just seems a bit wrong to me.

Previously, this was conditioned on 'transport->progress', but above
you unconditionally add the "-v" option. Seems like a bug.
