Fellas,

I got it to work :)

 I used the rstrip method from the string module to trim
trailing whitespace from the end of each line whenever a
document template gets saved. I tested it with DTML
Documents and Methods, which both worked fine. It doesn't
affect properties, so if you need to render trailing
whitespace for some reason you could store that as a
property.

The mods are listed below. If you use it, let me know what
you think and I'll write it up.

Cheers,
-Paul

Trim Trailing Whitespace Optomization
-------------------------------------
There were two changes to one file.
\lib\DocumentTemplate\DT_String.py

-from string import split, strip
+from string import split, strip, rstrip

...
def munge(self,source_string=None,mapping=None,**vars):
    """\
    Change the text or default values for a document
template.
    """

+    """ Optomization start - trim trailing whitespace to
reduce file sizes by 10-50% """
+    my_lines=split(source_string,'\n')
+    my_source=''
+    for my_line in
my_lines:my_source=my_source+rstrip(my_line)+'\n'
+    source_string=my_source
+    """ Optomization end """

    if mapping is not None or vars:
        self.initvars(mapping, vars)
    if source_string is not None: 
        self.raw=source_string
    self.cook()
