This has come up before for Git as well, see: https://public-inbox.org/git/1334140165-24958-1-git-send-email-bebar...@gmail.com/T/#u I see that your approach solves one of the shortcomings of those older patches, namely it makes possible to omit dangerous options from completion. Great. I also see that you want to invoke git in a subshell every time the user attempts to complete an --option. Not so great, at least for Windows users. That older thread contains a few ideas about how to do it only once by lazy-initializing a variable for each command to hold its options. > This is just a proof of concept.
