    **        straight up to this node.

    **        merge line, if this value exists.
    **    u:  Draw a thick child-line out of the top of this node and up to
    **        the node with an id equal to this value.  0 if it is straight to
    **        the top of the page or just up a little wasy, -1 if there is

    **        that the line is dotted instead of solid and has no arrow.
    **        Mnemonic: "Same Branch".
    **    f:  0x01: a leaf node.
    **   au:  An array of integers that define thick-line risers for branches.
    **        The integers are in pairs.  For each pair, the first integer is
    **        is the rail on which the riser should run and the second integer

    **        merges.
    **   ci:  "cherrypick-in". Like "mi" except for cherrypick merges.

** COMMAND: timeline
**
** Usage: %fossil timeline ?WHEN? ?CHECKIN|DATETIME? ?OPTIONS?
**
** Print a summary of activity going backwards in date and time
** specified or from the current date and time if no arguments
** are given.  The WHEN argument can be any unique abbreviation
** of one of these keywords:
**
**     before
**     after
**     descendants | children
**     ancestors | parents
**
** The CHECKIN can be any unique prefix of 4 characters or more. You
** can also say "current" for the current version.
**
** DATETIME may be "now" or "YYYY-MM-DDTHH:MM:SS.SSS". If in
** year-month-day form, it may be truncated, the "T" may be replaced by
** a space, and it may also name a timezone offset from UTC as "-HH:MM"
** (westward) or "+HH:MM" (eastward). Either no timezone suffix or "Z"
** means UTC.
**
**
** Options:
**   -n|--limit N         If N is positive, output the first N entries.  If
**                        N is negative, output the first -N lines.  If N is
**                        zero, no limit.  Default is -20 meaning 20 lines.
**   -p|--path PATH       Output items affecting PATH only.
**                        PATH can be a file or a sub directory.
**   --offset P           skip P changes
**   --sql                Show the SQL used to generate the timeline
**   -t|--type TYPE       Output items from the given types only, such as:
**                            ci = file commits only
**                            e  = technical notes only
**                            t  = tickets only
**                            w  = wiki commits only
**   -v|--verbose         Output the list of files changed by each commit
**                        and the type of each change (edited, deleted,
**                        etc.) after the check-in comment.
**   -W|--width <num>     Width of lines (default is to auto-detect). Must be
**                        >20 or 0 (= no limit, resulting in a single line per
**                        entry).
**   -R REPO_FILE         Specifies the repository db to use. Default is
**                        the current checkout's repository.
