Line ending, empty vs deleted, copies, renames, exec bits, merges, etc.

They're displayed by default.

The standard diff tool was created in 1974. Mercurial was created in 2005. So
asking why the diff format doesn't capture all the details is a bit like asking
why a VHS (1976) copy of a BluRay (2006) doesn't look as good.

We also support the Git format with -g which will show some but not all of the
aforementioned differences and also breaks some of the tools that work with
standard diffs.
