Tiger geocoder README (and unix loader suggestions)

[forkandwait]

Attached is a slightly edited version of the README, with any major new text in CAPS.

Besides stylistic things, I broke paragraphs by 2 newlines and re-wrapped the text to be 80 character or less lines (except for some code). Now it "looks right" when you open in it emacs, and it didn't before.

I also added instructions on outputting the script to a file from psql (basically "\a \t \o foo.sh" — but look in the text for details)

Also, I added text that recommended that the generated script be edited with "set -e -u" at the top to make it debug easier (this is basically like "use strict" in Perl — otherwise the script keeps running even if wget can't find a server, for example). This change should be folded into the SQL code, by someone who knows how that works.

Updated readme

[forkandwait]

In my README I suggested that "set -e -u" be added to the generated script because it will make the script stop if there is an error.

While this is great advice, I get errors when constraints are created that already exist if I run with "set -e", and the script just blows past them otherwise. There *may* be a problem with the generated code that "set -e" is uncovering (or it might be running the loader on a totally fresh DB would work, while I am trying to restart it).

Fixed at r7742. I also added a couple extra notes and changed the file to LF instead of carriage return so that should make it easier to read under Unix.

Fork, What is your real name?
