# Additional formatting options that we would like to use but cannot (at least
# yet):
#
# PPIndentWidth: 1
#     Better indentation of #if blocks, but unfortunately in Clang 13.0 this
#     indentation is also applied to code in #define macros, so produces:
#
#     #define ENTRY(args, flags)                     \
#      do {                                          \
#       if (args->debug)                             \
#        putil_log_entry((args), __func__, (flags)); \
#      } while (0)
#
#     Should be used as soon as there is a way to distinguish between
#     identation of the preprocessor directives themselves and the code blocks
#     in #define.
