Commit: https://github.com/vim/vim/commit/6a02eb073e1c801a5a92837d4b2d44b6a80afddd
Author: Christian Brabandt <cb@256bit.org>
Date: Thu Jan 25 22:28:37 2024 +0100
patch 9.1.0057: MS-Windows: Key event test still fails
Problem: MS-Windows: Key event test still fails
Solution: Skip testing CTRL-C, since it causes an Interrupt
which causes a test failure (after 9.1.0053)
