How does git diff –indent-heuristic work, and in what scenarios might it be useful?

The git diff command by itself is a powerful tool that shows the changes between two commits, branches, or even the changes between your working directory and the index. However, when changes in a file involve modifications that include indentation (for instance, adding or removing code within a conditional statement or a loop), the standard git diff output can sometimes be hard to read. This is because it tends to separate blocks of changes, leading to a diff output that is larger and harder to understand.
