This seems to be a upstream bug of vim. I tested several version of vim and results are as follows. 8.0.707 in debian stretch OK 8.0.1567 in cygwin NG 8.1.1240 in cygwin NG 8.1.1401 in debian buster NG 8.1.1551 in debian buster (local build) NG 8.1.1772 in cygwin NG 8.2.100 in cygwin (local build) NG -- Takashi Yano <takashi.y...@nifty.ne.jp> -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
