Incorrect selection of the next optional argument with tab character

[kliakos]

Take for example the function ListFirst(list [, delimiters]).

If I start typing, select the ListFirst function, enter the name "myList" for the first arg, and then press tab, it is selecting the "yList" of my list variable name + the "[, delimiters]".

This is an issue in the snippets package Snippets Issue 236 we can work around it by placing a space between the tab stops but that will has the effect of adding extra space inside the snippets.
