To reproduce:
$ touch foo.c foo.cc foo.cpp foo.h foo.m foo.mm
$ ./ci/format.sh
This will not check any file with clang, as the following command will do a
shell expansion and not find anything in git that matches:
$ git ls-files *.c *.cc *.cpp *.h *.m *.mm
* "Reland Clang 11, roll buildroot to 1bc40a5f916adb93d87e2a2230a0ec43db876c1c, take 4 (#17467)" (#17482)"
This reverts commit 8166a91bca11b83c16fba8f8fd407e937a2ac89c.
