Subject: vim-patch:8.2.2176: crash with a sequence of fold commands
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Problem:    Crash with a sequence of fold commands.
Solution:   Bail out when there are no folds at all.  Add a test (Dominique
            Pellé) (closes vim/vim#7515)

N/A patches for version.c:

vim-patch:8.2.2174: Mac version doesn't specify the CPU architecture

Problem:    Mac version doesn't specify the CPU architecture.
Solution:   Add "arm64" or "x86_64". (Yee Cheng Chin, closes vim/vim#7519)
https://github.com/vim/vim/commit/8c9d98a8af5351a3ac98cf11dede9f0268461511

vim-patch:8.2.2175: github actions: clang-11 handling suboptimal

Problem:    Github actions: clang-11 handling suboptimal.
Solution:   Separate step of installing clang-11. Get ubuntu release name
            dynamically. (Ozaki Kiichi, closes vim/vim#7514)
