[StGit PATCH 3/4] Let "stg show" use the unified --diff-opts handling

["Karl Hasselström" <kha@treskal.com>]

This introduces a small UI change: "stg show" called that flag
--show-opts. This could of course be avoided, but I don't think it's
worth it, since git-diff and git-show accept mostly the same options.
