Patch file parse error

All of a sudden, after over two years of working happily, I am getting an error when running `npm install`:

```
patch-package 6.5.1
Applying patches...

**ERROR** Failed to apply patch for package axios-https-proxy-fix

This happened because the patch file patches/axios-https-proxy-fix+0.17.1.patch could not be parsed.

If you just upgraded patch-package, you can try running:

patch -p1 -i patches/axios-https-proxy-fix+0.17.1.patch
npx patch-package axios-https-proxy-fix

Otherwise, try manually creating the patch file again.
```

[axios-https-proxy-fix+0.17.1.patch](https://github.com/ds300/patch-package/files/11525259/axios-https-proxy-fix%2B0.17.1.patch)

Seems to happen with many different versions on npm.

package.json includes this in the dev dependencies:

`"patch-package": "^6.5.1"`
