Have extract_summary omit the trailing newline.
Review Request #3019 — Created March 26, 2012 and submitted
Have extract_summary omit the trailing newline. It's not clear why the code had extract_summary put it in; reviewboard gives an error if the summary contains newlines. One of the code-paths that used extract_summary manually stripped the newline, but two others didn't.
(Manual. Let me know if it's appropriate to add a unittest case for this.)
