FWIW I looked at clang-format for gdb, but it wasn't suitable.  In
particular the way it reformats arguments to function calls is very bad,
and I couldn't find a way to make it better.  Here's an example bug:

https://bugs.llvm.org/show_bug.cgi?id=31907

I don't seem to have my .clang-format for gdb around any more.

I see gcc has one, but it also gives some sub-par results when run on
gdb.

It would be a big improvement if we could just use a tool.  However GNU
indent is apparently not maintained, and clang-format isn't a good fit.
