If I test the code snippet above with ipython/ptpython/python, I got the same
result as you described. But the problem I reported here is triggered by
running the command line wrapper of the project by `Ctrl-r`, which is worked

project, which may be pertinent to the problem discussed here.
But till now I still can't think of a solution.
