List Box Input: dot (.) as separator does not work.

I'm trying to use a dot (.) as separator in the List Box Input Quick form. However it always returns an empty table.

This is probably a bug? I suggest to allow dot as separator aswell.

Use case: pasting of SMILES with multiple components. 

If you copy multiple components from a drawing programming (ChemDraw, Marvin,...) each component will be separated by a dot according to SMILES specification. If dot can be uses as separator, this would make pasting SMILES (with multiple components) into a workflow very easy.
