Making things simpler

Inside every long shell script is a much simpler perl script waiting to get out. (some of my friends would say python or ruby instead, but the idea is the same). The recent changes to pg_indent that Bruce based on my work make it much simpler, and today I reached the stage where I decided to stop monkeying with the small script I use to set up builds of Postgres for development/testing and replace it with a much simpler perl script. It might take an hour to do but it will repay that very quickly.
