How to select linked without delimiting? When I use L to select linked vertices, there's a delimit option in the sidebar that I can't deselect. I want to select all linked vertices without a delimiter. How do I do that?

EDIT: This wasn't possible in v2.78. Selecting linked vertices without selecting a delimiter has been implemented in v2.79b!
In 2.79b at least, you can select multiple delimiters or deselect delimiters by shift LMB on the appropriate button.  With no delimiters enabled, it will only limit select linked by mesh connections.
