When editing it sometimes show the diff and sometimes only show the number of lines added.

Sometimes I see:

DIFF IS SHOWN HERE

In the example above it will show the diff.

Then we have the following as shown below, where it will not show the diff, instead it only shows the number of lines that has been edited:

$ apply_patch << 'PATCH'
* Begin Patch
* Update File: {filename}
│ … +17 lines
└ Success. Updated the following files: {filename}
DIFF IS NOT SHOWN HERE
