Hello, This is my first time reporting an issue with Git. I am not a native English speaker, so I apologize if there are any translation mistakes. Below is my response to `git bugreport`: > What did you do before the bug happened? (Steps to reproduce your issue) 1. I checked the `git mergetool --help` documentation and configured `$ git config --global mergetool.vimdiff.layout "@REMOTE"`. 2. In a repository with merge conflicts, I opened vimdiff using `git mergetool`, updated the REMOTE buffer, and saved the changes. > What did you expect to happen? (Expected behavior) I expected the changes made to the REMOTE buffer to be reflected in the file. > What happened instead? (Actual behavior) The changes made to the REMOTE buffer were **not** reflected in the file. > What’s different between what you expected and what actually happened? The documentation states: ”@ is used to indicate the file containing the final version after solving the conflicts. If not present, MERGED will be used by default.” So I thought that the changes made to the REMOTE buffer will be reflected in the file if I use @REMOTE. However, in my tests, @LOCAL and @MERGED worked as expected, but @BASE and @REMOTE did not behave correctly. > Anything else you want to add: I’ve uploaded a video reproducing this issue to a GitHub Gist.
