Yeah, agreed. FWIW, I'm not that fussed about this for .h/.c files,
since pgindent will fix it sooner or later (or even right away, if the
committer is anal enough to pgindent before committing, as some of us
are). It's a bit more of a problem for other file types.

I note that Peter E. seems to have a recipe for finding such issues,
which I suspect is grounded in some obscure git feature or other.
That might be easier to work with, since you'd only need one fix
not one per editor.
