Unfortunately, there is a class of tools which do not meaningfully change
source code, but result in an information-theoretical loss. indent(1) is a
prime example of this class. Running indent(1) on Free Source should not
make it non-Source.
There is also a class of tools which makes source effectively unmodifiable,
but is not information-theoretically lossy. For example, an obfuscator
which translates everything to C trigraphs. Running this on Free Source
makes it non-Source.
Finally, there is a very lossy conversion which must be Free, and that is
