postgresql/src/tools/pgindent

This can format all PostgreSQL *.c and *.h files, excluding libpq++,
*.y, and *.l files.

Get the list of typedef's included in pgindent by running this on the 
pgsql/bin directory:

	/src/tools/find_typedef

and update the list in pgindent.  This requires debug symbols.

From the top directory, run:

  find . -name '*.[ch]' -type f -print | egrep -v '\+\+|s_lock.h' | xargs -n100 pgindent

The stock BSD indent has two bugs.  First, a comment after the word 'else' 
causes the rest of the file to be ignored.  Second, it silently ignores
typedefs after getting the first 100.

Both problems are worked-around in this script.  We also include a patch
for the second bug in:

	/src/tools/pgindent/indent.bsd.patch

Even with the workaround, installation of the patch produces better
output.

GNU indent, version 2.2.6, has several problems, and is not recommended.
These bugs become pretty major when you are doing >400k lines of code.
If you don't believe me, take a directory and make a copy.  Run pgindent
on the copy using GNU indent, and do a diff -r. You will see what I
mean. GNU indent does some things better, but mangles too.

For java, we use astyle, http://astyle.sourceforge.net/, with the
following options:

	find . \( -name '*.java' -o -name '*.java.in' \) -print |
		xargs -n100 pgjindent

For cpp, we use astyle, http://astyle.sourceforge.net/, with the
following options:

	find src/interfaces/libpq++ -name '*.[ch]' -print |
		xargs -n100 pgcppindent
