When discussing formatting, we should keep the clang-format tool in mind
(  It's from the LLVM
project, and it's not under the GPL, but it is free software.  We should
adopt a standard .clang-format file for GNU code.  And, of course,
ideally someone would add the same functionality to GNU indent.

As far as the actual formatting goes, I don't see any reason not to
follow the format used by the GCC source code
(  To me it
seems like a straightforward extension of the GNU C formatting
