Preserving trailing spaces

[jgombos <nabble.forum.jog@spamgourmet.com>]

I know it's a strange request to want to preserve trailing spaces; most folks
want to nuke them.  I'm working on a project where trailing spaces actually
have meaning (it's how the developer prevents the automated semantecize tool
from concatenating a long line of code that's intended to span multiple
lines for readability).

They have (probably inadvertently) installed Apex Emacs (aka aemacs), which
is essentially plain old emacs 20.7.1 with Rational's Apex functionality
integrated into the menu.  I'm glad they provided it, but I'm the only emacs
user on the team, as everyone else is using the Rational's proprietary and
very basic editor.

So to get to the issue, emacs wipes out the trailing whitespace on every
file I make a change to, and the semantizer rearranges code that I didn't
touch, adding substantial noise to the diffs - which could frustrate
reviewers.  How do I prevent emacs from nuking the trailing whitespace?  

Everything I've read indicates that emacs automatically preserves
whitespace, and that it must be proactively configured to delete trailing
whitespace.  My .emacs file is clean.  So somewhere in this aemacs
installation, there must be a hook or something that I need to override. 
How would I discover where that's happening?  Is it the lisp code for
Ada-mode?
