I'm imaginging adding make / meson targets 'indent-tree' and 'indent-head' or
such. Obviously the buildsystem knows where the source dir is, and you'd
invoke it in the build dir, so it'd know all that'd need to be known.


Attached is a prototype adding such meson targets. It's easier with a
parameter telling pgindent where the source tree is, so I addeded that too
(likely would need to be cleaned up some).

I can't imagine that we'd remove support for doing so...
