Re: [PATCH 1/1] t5601: modernize test by using test_path_is_file

Hi!

Two things about your patch:

1. Given that you sent only a patch, you could do that without a cover
   letter, sending all the additional description that you want after 
   the scissors mark (the ---);

2. Your patch is adding the entire t5601.sh file. I could compare this
   with the file on the next branch, where I see that you indeed changed
   the line 69 for using `test_path_is_file`.

I suggest you to send a v2 containing only the changes that you did to that file, instead of a patch that creates this entire file.
