Reviewed-by: Carl Worth <cworth@cworth.org> Keith wrote all the code here against notmuch before notmuch.c was split up into multiple files. So I've pushed the code around in various ways to match the new code structure, but have generally tried to avoid making any changes to the behavior of the code. I did fix one bug---a missing call to g_mime_stream_file_set_owner in show_part which would cause "notmuch show" to go off into the weeds when trying to show multiple messages, (since the first stream would fclose stdout).
