[bug-diffutils] bug#70473: bug#70473: [PATCH] tests: fix stdin tests

[Tanmay]

Hi,

Thanks for replying!

I was using an older version (3.8) of diffutils on my machine, and I believe this feature was introduced recently. So, I thought it might be a bug. Now, I've grown more curious about how this feature is implemented to handle stdin. Implementing it without stdin seems fairly straightforward.

Looking forward to your response.

Thanks,

Tanmay

I don't see a bug there. In general 'diff DIRECTORY FILE' acts like
'diff DIRECTORY/FILE FILE'; here 'diff - a <d' acts like 'diff d/a a'.
