progress output is too long for Windows console #20122
Description
I did this
curld "https://google.com/test" --output out.out
I expected the following
a single line of progress data but sometimes there's multiple lines:
> curld "https://google.com/test" --output out.out
% Total % Received % Xferd Average Speed Time Time Time Current

0and here's what it looks like visually
bisected to 28380bb which changed the progress calculation. since then there have been other improvements but it seems that is the first commit when it started happening. it almost looks as if the progress line is 1 too many, and as a result when the \r goes to the beginning of the line it's already on the next line so it doesn't actually overwrite the intended line. notice the 0 only at the end there (which I assume is current speed)
EDIT: My console window size is set to 80x25. This is in Windows 11 and I'm using the regular console without the tabbed terminal thing. I could also reproduce in Windows 7 VM.
