Format include directive blocks and ordering with clang-format
Sort include directives within each block (separated by a blank line) in lexicographic order (except to prioritize `sys/types.h` first). First run `clang-format` with the config file: --- SortIncludes: false ... Commit the result temporarily. Then run `clang-format` again with: --- SortIncludes: true IncludeCategories: - Regex: 'sys/types.h' Priority: -1 ... Commit the result temporarily. Start a new branch and cherry-pick the second commit. Manually resolve conflicts to preserve indentation of re-ordered includes. This cleans up the include ordering without changing any other style. Use the following command to run `clang-format`: $ git ls-files -z -- \ '*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' | egrep -z -v '(Lexer|Parser|ParserHelper)\.' | egrep -z -v '^Source/cm_sha2' | egrep -z -v '^Source/(kwsys|CursesDialog/form)/' | egrep -z -v '...
