I would go one step further: vc-dired should not be based on dired at
all. 99% of the dired key bindings and functionality are not useful in
vc-dired. Plus that forces use to use the "v" prefix instead of using
simple key bindings.
vc-dired could instead use something based on ewocs. Looking at git.el,
implementing the status display using ewocs looks simple enough.
Sort term using dired is fine because it provide the much needed
multiple file commit functionality. But medium term it should be nuked
and replaced.
