Description

Thank you so much to all for developing the incredibly powerful Quarto! I am currently writing my master's thesis with your software, and I am only starting to grasp what it can do.

One thing I have noticed, is that it makes some changes to my .gitignore file, when I run quarto render for my quarto book project. You have already explained this further in this answer.

In my case, however, it adds /.quarto/ as an item to the .gitignore file, even though I already have .quarto in it. To my understanding of the syntax, the latter is even more "restrictive" than the former in the sense that it always excludes .quarto directories/files independently of where are they are stored relative to the .gitignore file.

I imagine that you still had you reasons for implementing it the way it is now. Why does quarto render not acknowledge .quarto as a .gitignore parameter?

Another aspect that I want to mention here is that having quarto render acknowledge the more restrictive .quarto exclusion would make it more consistent with the R command usethis::git_vaccinate(), since there the ignore parameter is also .quarto.
