'curl -s -S' is probably what you're after!

Quite amazingly, this is exactly what the new -w option does (introduced
in the upcoming 6.5). -w takes a string and has a bunch of variable
substitutions to enable you to select what to see.

I can see the point in having a feature like this.

I don't see how this can be added to -s (-sx can't be used since that
would be -s and -x written next to each other and -x is already used).

I could however think of a -w -style option where you specify what kind of
line you want to get written intead of the progress meter line with a
steady interval. I would then suggest -W or possibly using the -w for the
format and another flag to enable the interval-output.

This will need a little thinking and debating.
