Patch fails to apply (sometimes silently) when patch includes additions to the end of a file

[lukebatchelor]

Hiya,

We stumbled across a bit of a weird edge case that we thought you might like to know about. After doing some digging, it appears the required steps to reproduce are:

• the file you are patching has no newline at the end of it
• you are adding another line to the end of that file (still with no newline)

I can't link the original patch we were working on, but I've reproduced it here: https://github.com/lukebatchelor/patch-package-repro

We had a brief look at trying to fix this (originally assuming patch-package was using git-apply under the hood and hoping we could just pass on the --inaccurate-eof flag but alas you weren't. It does look like you have explicit code for handling this so likely just a small edge case in that logic.

Hope this helps, thanks for making this package

Facing this exact issue but only when running on Docker. Running the patches locally works perfectly fine. But running them via docker causes this issue.
