+If set to non-zero, this will enable line wrapping on the tagbar window. This
+option will use the built-in |wrap| vim option on the tagbar window to
+enable line wrapping. This also will use the |breakindent| and
+|breakindentopt| options in vim to set the indentation of the wrapped lines.
+
+Note: This requires VIM to be compiled with the |+linebreak| option for the
+wrap intentation to function.
