post-review.py
1. edit an XML file in SVN containing comments like this:
<!--
-->
remove the comments with an editor.
2. use post-review.py to post the file.
3. In the resulting review, use the "View Diffs" button. The server
displays an error. The error is because the diff posted by the
post-review.py script is corrupt. The diff is corrupt because the method
"handle_renames" mangles the "-->" string and eliminates it because it is
looking indiscriminately for the string "---" in the diff.
What operating system are you using? What browser?
