List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 03 Feb 2012 22:41:19 -0000 Use the new notmuch argument parser to handle arguments in "notmuch show". There are two corner case functional changes: 1) Also set params.raw = 1 when defaulting to raw format when part is requested but format is not specified. 2) Do not set params.decrypt if crypto context creation fails.
