Some typography conventions use an em-dash at the start of a paragraph line to denote a speaker change in a dialogue. This is the case in particular in French and Turkish typography. All spaces following an em-dash at the beginning of a paragraph in the input should be replaced by a single fixed inter-word space, so that subsequent dialogue lines all start identically, while other inter-wordspaces may still be variable for justification purposes.

Class speakerChangeNode
- speakerChangeNode:shape ()
-
Shape the node.
The typesetter can insert this node when it detects a speaker change
at the start of a paragraph, i.e. an em-dash followed by some space.
The typesetter is responsible for passing the correct text to this node,
i.e. the em-dash followed by a regular space, as in "— Some dialogue".
This special unshaped node subclass, when shaped, replaces the
shaped space (now a glue) by a fixed-width kern.
Returns:

Array of shaped nodes (nnodes, glues, penalties...)
