Re-downloads media attachments from other servers. You must specify the
source of media attachments with one of the following options:
Use the --status option to download attachments from a specific status,
using the status local numeric ID.
Use the --account option to download attachments from a specific account,
using username@domain handle of the account.
Use the --domain option to download attachments from a specific domain.
Use the --days option to limit attachments created within days.
By default, attachments that are believed to be already downloaded will
not be re-downloaded. To force re-download of every URL, use --force.
