Identifying identical files

[Andrew-Hanlon]

Thank you for the great work you put into this port - it seems to run very efficiently.

I have been reading over the format, and am just wondering if you can confirm my understanding:

• If the origin and target are the same then the byte stream will always start with [Size]\n[Size]@0,. Meaning that the full set of bytes is a copy.

Is checking for this condition the best approach to identify files (post diff) that are identical?
Edit: Is there the possibility of flagging this condition to optionally return an empty byte array?

My scenario is where I have an archive of file diffs, and I want to be able to simply write a zero byte file so that I can bypass Applying them altogether later-on and simply perform a straight copy.

Thanks.

Hi @Andrew-Hanlon,

Thanks for checking out this project. I'm all in for this feature.
At the moment I won't have time for this, unfortunately. :(

A pull-request is very appreciated! Cheers!
