cli: convert "notmuch show" to use the new argument parser
Use the new notmuch argument parser to handle arguments in "notmuch show". There are three minor functional changes: 1) Also set params.raw = TRUE when defaulting to raw format when part is requested but format is not specified. This was a bug, and --part=0 without --format=raw did not work previously. 2) Set params.decrypt = FALSE if crypto context creation fails. 3) Only use the parameters for the last --format if specified multiple times. Previously this could have resulted in a non-working mixture of parameters. Signed-off-by: Jani Nikula <jani@nikula.org>
