Previously staged bump and changelog should be committed on subsequent execution

[mentAl-maZe]

Steps to reproduce:
Starting from v1.0.0 with a previous feature commit

$ npx standard-version --skip.commit --skip.tag`
✔ bumping version in package.json from 1.0.0 to 1.1.0
✔ outputting changes to CHANGELOG.md
$ npx standard-version --skip.bump --skip.changelog`
✔ committing %s
✔ tagging release v1.1.0
ℹ Run `git push --follow-tags origin test/standard-version` to publish

Or with intermittent steps:

$ npx standard-version --skip.commit --skip.tag`
✔ bumping version in package.json from 1.0.0 to 1.1.0
✔ outputting changes to CHANGELOG.md
$ echo "test" | tee newFile.txt && git add newFile.txt
test
$ npx standard-version --skip.bump --skip.changelog --commit-all`
✔ committing all staged files and %s
✔ tagging release v1.1.0
ℹ Run `git push --follow-tags origin test/standard-version` to publish

Notice:

• ✔ committing %s in the first example
• ✔ committing all staged files and %s in the second example

Expected:
Previously staged files are committed with automatic commit message and tagged after commit.

Actual:
Nothing is committed, files remain staged, tag is applied to HEAD

Workaround:

Stage changelog on second execution with --commit-all flag

$ npx standard-version --skip.commit --skip.tag --skip.changelog
✔ bumping version in package.json from 1.0.0 to 1.1.0
$ echo "test" | tee newFile.txt && git add newFile.txt
test
$ npx standard-version --skip.bump --commit-all
✔ outputting changes to CHANGELOG.md
✔ committing CHANGELOG.md and all staged files
husky > pre-commit (node v10.16.0)
No staged files match any of provided globs.
husky > commit-msg (node v10.16.0)

✔ tagging release v1.1.0
ℹ Run `git push --follow-tags origin test/standard-version` to publish

I have the same issue, I'm trying to first create a draft release and manually edit the changelog if needed and then commit and push the release in a separate step.
The output from my draft release step (standard-version --skip.tag --skip.commit) is not committed at all when running:

standard-version --skip.tag --skip.changelog --skip.bump --commit-all
