Tikz: Align Drop Line to left of box when single line of text is present in node

Question

I am playing with the example from Tikz located here. When I change the text from "Defining nodes and arrow styles" to "Defining nodes" the line dropping to the children of this node shifts to the right.

Is there a way to make the line always be set to the left of the box surrounding "Defining node" like when there are two lines of text?

Answer 1

The trick to making sure the trailing lines were always to one side of the next level, in this case forcing the line to shift to the left of the "Defining node" block, is simply a switch from

c1.195

to

c1.west

in the \foreach statements seen in the example of the original post.
