描述
Bug report
With the following in ~/.editrc:
bind "^R" em-inc-search-prev
Pressing CTRL+R inside the macOS-bundled python (/usr/bin/python3, which is compiled against editline) to enter editline history, and then pressing CTRL+C does not properly remove "bck" and does not write KeyboardInterrupt until CTRL+C is pressed two more times for a total of three times.
In other words, inside an editline history search, CTRL+C needs to be sent three times to get back to the normal REPL state.

调研方向
在 macOS 自带的 /usr/bin/python3 REPL 中,使用所述的 ~/.editrc 绑定复现该问题,然后跟踪 editline 历史搜索和 CTRL+C 处理的入口点。完成的标准是:按一次 CTRL+C 即可干净地退出历史搜索并写入 KeyboardInterrupt,而不是需要按三次。
