Feature request: more completions!

Some commands I use often that aren't currently suggested (or need 90% of the typing to be suggested):

git rebase -i $(git merge-base HEAD master) - this one is a stretch
git rebase -i master - bit will not complete master, you have to type it in yourself
git status - for some reason typing st shows pull --rebase origin master before commands starting with st?
git show - same bug, shows commands that don't start with sh before show
git checkout <branch> -- file - bit will complete up to <branch> but not further
git checkout -p; git add -p - bit will not show -p in the initial list. This one is a stretch.
git log <branch> - bit will not complete <branch>. It would also be nice to complete file names.
git diff --cached - diff needs up to dif to complete and --cached isn't suggested at all
git worktree add - bit will complete up to worktree but no further
