Working with Git staging can set binary files to 0 bytes

[tcwalther]

Summary

Editing a binary file, like an image, while working with the Git pane in Zed can lead to the file becoming 0 bytes large.

Description

I have tried to reproduce this in a small, new project, but can't get the error to show again. Here's what happened:

1. I added images to my project.
2. I staged them using the Git pane in Zed
3. I compressed the images using ImageOptim, thereby changing them on disk.

Expected Behavior: the images should compress, and should be able to stage the updated images Actual Behavior: one of the images became 0 bytes large.

This happened several times, always on the same images. When trying this again on a new, fresh project, I can't reproduce it. I can't find any relevant error in the Zed logs either. I still wanted to submit this bug in case someone else can reproduce it or at least stumbles over a similar issue. Maybe we can start narrowing down what causes this.
