Revert "Fix cursor move with wide glyphs"
This reverts commit 7473a8d1a57e5f9aba41b953f4e498c35e1c9dc5. This patch needs some more work. It caused regressions with programs that use GNU readline, etc. Original test-case example from Tim Culverhouse <tim@timculverhouse.com>: printf " 😀" && sleep 2 && printf "\e[D" && sleep 2 && printf "\e[D" && sleep 2 After the patch it caused regressions, example test-case: printf "A歗\bB\n"
