When `git diagnose` is run from outside a repo, it begins collecting various information before eventually hitting a segmentation fault, leaving an incomplete zip file behind. Switch from the gentle setup to requiring a git directory. Without a git repo, there isn't really much to diagnose. We could possibly do a best-effort collection of information about the machine and then give up. That would roughly be today's behavior but with a controlled exit rather than a segfault. However, the purpose of this tool is largely to create a zip archive. Rather than creating an empty zip file or no zip file at all, and having to explain that behavior, it seems more helpful to bail out clearly and early with a succinct error message.

I haven't found anything in the original submission [1] discussing this "_GENTLY". I didn't see anything in the implementation or the tests suggesting that it was intentional to run outside a git repo.
