This patch set allows a user to specify a list of tags to be added/removed to messages discovered during "notmuch new".
Two use-cases are envisaged: 1) A chunk of messages was just dumped into the configured directory by hand, and the user doesn't want the 'inbox' tag applied to them. Run 'notmuch new -inbox'. 2) A periodic mail processing script wants to add new messages to the database, then process those newly added messages to add convenience tags, etc. without worrying about the user or other instances of the script manipulating tags at the same time. Use this approach: KEY=$RANDOM notmuch new +$KEY notmuch tag +notmuch tag:$KEY and to:notmuch at notmuchmail.org notmuch tag +gnus tag:$KEY and to:ding at gnus.org ... notmuch tag -$KEY tag:$KEY
