feat(git): make `wd` alias more useful
feat(git): make `wd` alias more useful

Because I often want to pass params like a limit of 0 but I can't really
do that the way this alias is put together, just bake in a set of mostly
useful params and let the rarer use cases be handled by a manually `git
diff --dirstat` invocation instead.

(99% of the time, I just want to know what modules to deploy without the
risk of any false negatives, so this new alias will serve me well in
that common case.)
