INSTALL.txt clarifications

I don't have time at the moment to work on this, but here's a blurb that just took place in #drupal-support:

<xmt> hi, i installed drupal under linux. the installation guide tells me i have to create a database. but this does not work:
<xmt> mysqladmin -u dba_user -p create drupal
<xmt> Enter password:
<xmt> mysqladmin: connect to server at 'localhost' failed
<xmt> error: 'Access denied for user 'dba_user'@'localhost' (using password: YES)'
<xmt> i think there is no user dba_user in mysql
<xmt> do i have to create a drupal db user? how?

A note should probably be added that "dba_user" should be replaced with whatever their mysql username is (or root, if none have been defined yet).

<xmt> next difficulty is this:
<xmt> GRANT ALL PRIVILEGES ON drupal.*
<xmt> TO nobody@localhost IDENTIFIED BY 'password';
<xmt> so nobody is root in my case?

It should probably also be made clear that this GRANT ALL .... will create a new user called 'nobody' if it does not already exist.

I know these points are pretty obvious for people who've been working with MySQL for awhile, but it's obviously tripping up some of the newbies out there, and a little rewording wouldn't hurt.

As a side note, GRANT ALL?? That seems a little overly generous?

Additionally, there are approximately 80 kabillion comments on this handbook page:
http://drupal.org/node/260

...which probably need to be gone through to see what is outdated and what should make it into INSTALL.txt.
