Re: [PATCH 0/2] MR5194: cmd/tests: Add tests for calling special excuteable files.

[Haidong Yu (＠yhd986)]

I tested in win7 and win10. the result is follow(diffent from your test):
```
C:\Users\epo>echo @echo foo > echo_.bat
C:\Users\epo>echo_ bar
foo
C:\Users\epo>echo_.bat bar
foo
@rem while '_' isn't used as a keyword delimiter
```
