Display file mode changes #23021
Description
Feature Description
Git stores two possible file modes: not executable and executable (AFAIK) when enabled (git config core.fileMode [true|false]).
Sometimes, a commit (and then subsequently a PR) changes the file mode of a file.
At the moment, the user is not informed that the file mode has changed, instead they see that a file inside the changed files without any changes (assuming no other changes).
If (and only if) this mode has been changed, the new (and old) mode should be shown for this file of the PR/ commit you are viewing.
At the moment, this is also a point of error as a changed file mode won't be noticed in a PR, thus potentially leading to subsequent client-side errors.
