Bash命令`Ctrl + u`截斷當前輸入行而不是清除它

Question

這些天我遇到了一個奇怪的Bash問題。在終端中，當我按下命令ctrl+u並且想要清除當前輸入行而不是清除它時，有時它會截斷當前輸入行，從一開始就保留某些字母。

例如，在下面的例子中，我先按4次ctrl+p找到最近輸入的命令。然後當我停在ls /Users/Heros/dev/gitinspector/gitinspector-0.3.2命令。現在我按ctrl+u。當前輸入行未完成清除，如圖所示。它在那裏留下ls /Users。

我一直googling這個問題幾天，但沒有運氣。有人遇到過類似的問題嗎？提供的任何線索將很感激，提前感謝。

順便說一句，我使用Bash和我使用的終端是iTerms2。我嘗試了標準的終端應用程序，問題仍然存在。

協助調查，我貼我使用~/.bash_profile，在情況下，它會有所幫助。

最後，我得到一個解決方法，僅通過禁用color_my_prompt功能，問題消失了。我之前從網上覆制這個功能，目前我不知道它有什麼問題。

任何人找到根本原因，我會接受你的答案，謝謝。
