Steps to reproduce

Set some margins first by running printf '\033[1;20r' and then reset margins by running printf '\033[r'.

Expected Behavior

After reset margin is run, contour should set margins to pagesize.

Actual Behavior

Contour doesn't reset margins and keeps the original margins that were given in previous DECSTBM invocation.

oh wow. how did you find that out? how did that bug end up in here? 🤔

EDIT: This is a case that really wants a test case added, once fixed. :)

I was testing one of j4james' script and found that contour doesn't work as expected and margin reset was the reason.

Same behavior exists in DECSLRM.
