  "When t, make TAB cycle visibility on plain list items.

Cycling plain lists works only when the cursor is on a plain list
item.  When the cursor is on an outline heading, plain lists are
treated as text.  This is the most stable way of handling this,
which is why it is the default.

When this is the symbol `integrate', then during cycling, plain
list items will *temporarily* be interpreted as outline headlines
with a level given by 1000+i where i is the indentation of the
bullet.  This setting can lead to strange effects when switching
visibility to `children', because the first \"child\" in a
subtree decides what children should be listed.  If that first
\"child\" is a plain list item with an implied large level
number, all true children and grand children of the outline
heading will be exposed in a children' view."
