patch-commit doesn't work as expected when change a file which has no newline at end of line

[await-ovo]

pnpm version:

$ pnpm -v
7.11.0

Code to reproduce the issue:

1. run pnpm patch safe-execa@0.1.2
2. append some text to lib/index.js in given temp directory like following:
   
3. run pnpm patch-commit <temp dir>
4. you can see that node_modules/safe-execa/lib/index.js become as follows:
   

Expected behavior:

All changes should be synced to node_modules/safe-execa when the commit is executed.

Actual behavior:

Last line of editing is missing.

Additional information:

As far as i know, When the modified file does not have EOL , git diff ends with \ No newline at end of file. I tried ignore it , and patch-commit works fine. I'm not sure if it's more appropriate to handle this situation during the installation process, thanks a lot~
