I have a file.
I have another file on a different path on a different branch with mostly the same content.
I have changes in my first file.
I want to move these changes to my second file.
The files have the same name, only the path differs.
(I also need to ignore changes in whitespace, because consistency.)
git show SHA_HASH --relative=original/path/ -- original//path/file.name | git apply --directory=new/path/ --ignore-space-change -
