Good catch. But I don't see a difference in the commit-message editor. Tabs have already been rendered.

How do you mean? If you go to reword a commit and put some tabs in the editor, you will not see them, but they exist (can be deleted accordingly i.e. press tab 7 times, you will have to delete or traverse with arrow keys 7 times to account for it).

Good catch

... that the changed submodule is not used yet.

1. I missed that the original issue was just about rewording commits. Other usages of TextEditor are able to display tabs (FormCommit and F4).
   That's why there was no need to alter the submodule.
   But you are going to enable it by default. 👍
2. If testing the portable build, the git config for file editor must be updated manually. Works 👍.

I also had some problems to find the issue...
