Sure, but what should I call it, then? Just `marlon`? (Seeing as we already have `adam`, `bart`, etc. themes.)

A preset variable would be great. In C code, you can get the names and values from `sysexits.h`, which is available in both GNU and BSD.

It would be great if, besides printing the name, it could also add a short description of what the exit code actually means. Something like “SIGPIPE (140): write on a pipe with no reader”.

Please show me another way to theme the VCS part of the prompt and I will use that.

What would be a better practice?

Sure, I will add those.

After setting it to '%B%F{red}*%b%f’, yes.

Sorry, but what does NIH stand for? (I’m guessing you don’t mean the National Institutes of Health.)

Because it’s a theme? If people wanted to style their vcs_info directly, then why would they use a theme? Conversely, VCS info is the number one thing that new users want to add to their prompt. I don’t think it’s unreasonable to expect that to be included out of the box. Nearly all of 3rd-party prompt themes in the wild include at least Git info.

Sure, I’ll start a separate patch thread for those.
