Well, to start with it provides a nicer way to invoke pgindent for the
whole repo.

And it will be relatively easy to incorporate new stuff, for example
what Greg Smith was doing in his wrapper script.

It's true that the script contains an unfortunately large number of
workarounds for the limitations and failure modes of the patched bsd
indent we've been using. Some of those are currently working less than
perfectly, and I found it fairly difficult to understand exactly what
they were doing. I hope what I have produced will be a bit clearer and
more maintainable than what it replaces, as well as working a bit better
and more robustly.

Yes, which is why I decided to do this - I certainly don't currently
have time to re-implement indent.
