I am excited Andrew has done this. It has been on my TODO list for a
while --- I was hoping someday we could switch to GNU indent but gave up
after the GNU indent report from Greg Stark that exactly matched my
experience years ago:

http://archives.postgresql.org/pgsql-hackers/2011-04/msg01436.php

Basically, GNU indent has new bugs, but bugs that are harder to work
around than the BSD indent bugs.

Once I heard that I realized we were going to be using BSD indent for
many more years to come and rewriting the shell script in Perl was the
next logical step, which Andrew has done.

This will also allow us to use pgindent on Windows that has Perl
installed --- we should create a DOS binary of bsd indent so Windows
users scan run it.

I would also like to add a command-line way to detect our patched
version of BSD indent so we know we are using the right binary. I will
do that once the Perl version is committed to git.

Thanks Andrew.
