[5.0.2] test_sip_hst fails: additional parameter A_2_2

See original GitHub issue

Description

When trying to package 5.0.2 for Debian, I observed a failure for test_sip_hst() in that str(sip) returns one additional parameter.

Actual behavior

I don’t know whether this is similar to #12948 connected to a different line width or a real difference. Since the assert repr(sip) passes, this is probably really a problem with the representation in __str__.

I see the same issue on 5.0.1.

The problem is really the width of the terminal: when I start it in a 80x24 terminal, it works fine while on a bigger one this (and #12948) fail (GNOME-Terminal 3.34.90, width=136 chars as an example).

@olebole try #12953 and see if that fixes your bugs. Please leave a review reflecting your findings.
