**    a=DATETIME Only show changes after DATETIME
**    b=DATETIME Only show changes before DATETIME
**    m=HASH     Mark this particular file version
**    n=NUM      Show the first NUM changes only
**    brbg       Background color by branch name
**    ubg        Background color by user name
**    ci=HASH    Ancestors of a particular check-in
**    orig=HASH  If both ci and orig are supplied, only show those
**                 changes on a direct path from orig to ci.
**    showid     Show RID values for debugging
**
** DATETIME may be "now" or "YYYY-MM-DDTHH:MM:SS.SSS". If in
** year-month-day form, it may be truncated, 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.
