[Bug?]: Problem with applying patch if there is "No newline at end of file"

[adam-sajko]

Self-service

• I'd be willing to implement a fix

Describe the bug

Here is the strange situation I had. I created and applied the patch, but it looks like if my changes are at the end of the file and there is \ No newline at end of file fragment in the patch (which is generated by the patch) then the patch doesn't apply the last line.

Context

I made a patch for @tamagui/web for v0.117.0:

• I forked the original repo
• I made changes in the original files
• I run the build to get compiled files
• I went to my project folder
• I created a temporary patch folder with yarn patch @tamagui/web
• I copied compiled files to that folder
• I created a patch with yarn patch-commit -s
• I double-checked all files and the patch to make sure everything is ok
• I ran the app and I received an error

The issue was because there was no "}" and the end of node_modules/@tamagui/web/dist/cjs/helpers/getSplitStyles.cjs. This file btw. was generated by the tamagui build process when I was preparing the files for the patch, so I didn't make any manual changes in this file, and the patch, so we can exclude any human mistake.

Everything works fine after removing this line \ No newline at end of file. Or if I added manually a new line in the file for the patch.
