Vim - editing tar and tgz files

Question

I'm embarrassed to say, after a couple of decades of using vim, I've only just discovered you can open, browse, and look at tar, and tgz files in vim (although in fairness, I think that this is quite a recent add-on)

(if you haven't discovered this feature yet by the way, it's very cool)

Does anyone know if one can edit files the files in tar files, and have vim repack them back into the archive.

The plugin page and This SO question Seems to suggest it's read only, but I wondered if there was a way to do this.

Answer 1

just tried this at work and it actually works - perhaps I had an older version of VIM at home.
