** SETTING: timeline-block-markup      boolean default=off show-only-if-changed
**
** If enabled, block markup (paragraph brakes, tables, lists, headings, etc)
** is enabled while rendering check-in comment message on the timeline.
** This is disabled by default, because the timeline works best if the
** check-in comments are short and do not take up too much vertical space.

/*
** SETTING: timeline-hard-newlines     boolean default=off show-only-if-changed
**
** If enabled, the timeline honors newline characters in check-in comments.
** In other words, newlines are coverted into <br> for HTML display.
** The default behavior, when this setting is off, is that newlines are
** treated like any other whitespace character.
