Autopep8不会中断较长的注释行吗？

Question

我尝试使用autopep8格式化某些python代码，期望除其他事项外，分隔超过80个字符的注释行。我使用了这个测试文件test.py，该文件仅包含注释：

#asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf
#asdf asdf asdf asdf
#asdf asdf asdf asdf

#asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf
#asdf asdf asdf asdf
#asdf asdf asdf asdf
#asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf

然后我跑了 autopep8 test.py

这给出以下输出：

# asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf
# asdf asdf asdf asdf
# asdf asdf asdf asdf

# asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf
# asdf asdf asdf asdf
# asdf asdf asdf asdf
# asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf
# asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf

最后的长行被分割，但前两行没有。我认为所有行都应以80个字符的宽度折断。我究竟做错了什么？

autopep8不会自动修复所有长行；仅在被视为“安全”的情况下才这样做。参见：https : //github.com/hhatto/autopep8/issues/39
