Feature Description

Compelling research exists to suggest that the histogram diff algorithm is much superior to myers. This makes diffs smaller and easier to read in various edge cases. If histogram is not available, patience is close but less performant.

If this request is denied, could you please advise how to alter a server setup to use this? i.e., which .gitconfig file should I change?

This was discussed in the past in https://github.com/go-gitea/gitea/issues/20467 and I generally think it is a welcome change.

In which git version was histogram introduced?

Actual change can be done around here: https://github.com/go-gitea/gitea/blob/main/modules/git/git.go#L205.
