pgindent cleanup

Following up Tom's complaint about behaviour of pgindent, I have been
wrestling with it a bit. I noticed several things.

First awk on my box spits out fairly useless warnings about regular
expressions containing a literal '\*'. These warnings are silenced by
replacing those with '[*]', which should have the same effect.

Second, the script issues warnings about how somebody hopes that I
installed indent.bsd.patch. Yes I did, and the messages are just
annoying noise, so I propose to get rid of them. The usual rule of unix
utilities is to be silent on success, and I think we should follow it.

Third, as mentioned in that other thread I think we should put the
exclusion of certain typedef symbols into the pgindent script.

The attached patch does all three of these things.

I'm not done yet - I am seeing issues with at least two files:
contrib/fuzzystrmatch/dmetaphone.c and
src/backend/tsearch/wparser_def.c, that I need to chase down.

Ideally, this hodegpodge of awk and sed pipes would be replaced by a
perl script that would do all that inline much more efficiently, along
with some more features. But that's a longer term project.

Looks fine to me.
