Oh yes. Do not muck with the files in the .svn directory! I believe
if the file in the text-base directory of the .svn directory has the
same mtime as the corresponding real file, then the checksums aren't
even checked, or something like that. And if the sed/awk completed in
< 1 second this is what would happen.
