Indentation and whitespace /tend/ to be insignificant to the operation
of the code.  Of course, presence in string literals is a different
story -- where even replacing tabs with spaces is a hazard.

 From a quick look, it seems like the problem goes beyond that.
Note that the leading 'X' is stripped from most -- but not all -- lines
of "encoded" files.

As you appear to be the owner of the file (and presumably have another
copy stashed away), you might try reposting it as a SHAR but uuencoded,
first.  I would suspect that would be more robust wrt whatever pretty-printing
algorithm google is trying to impose.

Or, just keep a copy on some other public archive.
