 Allows you to edit, add, or remove the task statuses available in Maniphest,
 like "Open", "Resolved" and "Invalid". The configuration should contain a map
 of status constants to status specifications (see defaults below for examples).
 
 The constant for each status should be 1-12 characters long and  contain only
 lowercase letters and digits. Valid examples are "open", "closed", and
 "invalid". Users will not normally see these values.
 
 The keys you can provide in a specification are:
 
   - `name` //Required string.// Name of the status, like "Invalid".
   - `name.full` //Optional string.// Longer name, like "Closed, Invalid". This
     appears on the task detail view in the header.
   - `name.action` //Optional string.// Action name for email subjects, like
     "Marked Invalid".
   - `closed` //Optional bool.// Statuses are either "open" or "closed".
     Specifying `true` here will mark the status as closed (like "Resolved" or
     "Invalid"). By default, statuses are open.
   - `special` //Optional string.// Mark this status as special. The special
     statuses are:
     - `default` This is the default status for newly created tasks. You must
       designate one status as default, and it must be an open status.
     - `closed` This is the default status for closed tasks (for example, tasks
       closed via the "!close" action in email or via the quick close button in
       Maniphest). You must designate one status as the default closed status,
       and it must be a closed status.
     - `duplicate` This is the status used when tasks are merged into one
       another as duplicates. You must designate one status for duplicates,
       and it must be a closed status.
   - `transaction.icon` //Optional string.// Allows you to choose a different
     icon to use for this status when showing status changes in the transaction
     log. Please see UIExamples, Icons and Images for a list.
   - `transaction.color` //Optional string.// Allows you to choose a different
     color to use for this status when showing status changes in the transaction
     log.
   - `silly` //Optional bool.// Marks this status as silly, and thus wholly
     inappropriate for use by serious businesses.
   - `prefixes` //Optional list<string>.// Allows you to specify a list of
     text prefixes which will trigger a task transition into this status
     when mentioned in a commit message. For example, providing "closes" here
     will allow users to move tasks to this status by writing `Closes T123` in
     commit messages.
   - `suffixes` //Optional list<string>.// Allows you to specify a list of
     text suffixes which will trigger a task transition into this status
     when mentioned in a commit message, after a valid prefix. For example,
     providing "as invalid" here will allow users to move tasks
     to this status by writing `Closes T123 as invalid`, even if another status
     is selected by the "Closes" prefix.
   - `keywords` //Optional list<string>.// Allows you to specify a list
     of keywords which can be used with `!status` commands in email to select
     this status.
 
 Statuses will appear in the UI in the order specified. Note the status marked
 `special` as `duplicate` is not settable directly and will not appear in UI
 elements, and that any status marked `silly` does not appear if Phabricator
 is configured with `phabricator.serious-business` set to true.
 
 Examining the default configuration and examples below will probably be helpful
 in understanding these options.
