I have attached a small filter module that strips leading whitespace from text files.

Well, we've had people submit modules in the past that stripped the extraneous whitespace from HTML files, and we rejected them. Check the archives for messages from a guy named fabio rohrich, who wrote a module called mod_blank to see why that might have been. I don't completely remember the details.
In a nutshell,
it is very hard to strip whitespace out of HTML, and have the resulting file still be as valid as the old one. Browsers are very forgiving on something and not on others. for example,
you should not strip code inside of javascript, or 'pre' tags.
