Zsh VCS_INFO backend (shell prompt status) for jj

[dblsaiko]

The shell prompt I use (part of grml's zshrc) uses Zsh's VCS_INFO system (see zshcontrib(1)) to display VCS status prompt. I wrote a basic backend for jj for that, posting here for any other Zsh users to make use of it.

Here's a sample log I just pulled out of my terminal, this is how it displays with grml's zshrc. Most of the text (in the brackets) is pulled as-is from jj status, except for empty working copies which get displayed as the parent bookmarks/change suffixed with a '+'.

Great, you could add that info in the Wiki: https://github.com/martinvonz/jj/wiki/Shell-Prompt

Good work. Ended up using it. Works well with zap-prompt.

@2xsaiko maybe this is something you could contribute to Z Shell itself?
