Preserving collections

Collections seem to go away on their own after a while.  Is there a
way to save the collection, so that a link can point to the PDF or ODF
versions?

Also, the pre element gets mangled in the ODF conversion so that lines
get wrapped and merged rather than left as-is.  Thus

    Subsystem sftp internal-sftpMatch Group sftp-only
        ChrootDirectory %h
        AllowTCPForwarding no
        X11Forwarding
        ForceCommand internal-sftp

gets wrapped incorrectly to

    Subsystem sftp internal-sftpMatch Group sftp-only
ChrootDirectory %h
    AllowTCPForwarding no        X11Forwarding         ForceCommand
internal-sftp
