 When text is deleted and a text property no longer includes any text, it is
 deleted.  However, a text property that was defined as zero-width will remain,
 unless the whole line is deleted.

+When a buffer is unloaded, all the text properties are gone.  There is no way
+to store the properties in a file.  You can only re-create them.  When a
+buffer is hidden the text is preserved and so are the text properties.  It is
+not possible to add text properties to an unloaded buffer.
 
 When using replace mode, the text properties stay on the same character
 positions, even though the characters themselves change.
